The Elves are very busy pushing things around in [1m[97mcarts[0m on some kind of rudimentary system of +tracks they've come up with. + +Seeing as how cart-and-track systems don't appear in recorded history for another 1000 years, the +Elves seem to be making this up as they go along. They haven't even figured out how to avoid +collisions yet. + +You map out the tracks (your puzzle input) and see where you can help. + +Tracks consist of straight paths (| and -), curves (/ and \), and intersections (+). Curves connect +exactly two perpendicular pieces of track; for example, this is a closed loop: + +/----\ +| | +| | +\----/ + +Intersections occur when two perpendicular paths cross. At an intersection, a cart is capable of +turning left, turning right, or continuing straight. Here are two loops connected by two +intersections: + +/-----\ +| | +| /--+--\ +| | | | +\--+--/ | + | | + \-----/ + +Several [1m[97mcarts[0m are also on the tracks. Carts always face either up (^), down (v), left (<), or right +(>). (On your initial map, the track under each cart is a straight path matching the direction the +cart is facing.) + +Each time a cart has the option to turn (by arriving at any intersection), it turns +[1m[97mleft[0m the first time, goes [1m[97mstraight[0m the second time, turns [1m[97mright[0m the third time, and then repeats +those directions starting again with [1m[97mleft[0m the fourth time, [1m[97mstraight[0m the fifth time, and so on. This +process is independent of the particular intersection at which the cart has arrived - that is, the +cart has no per-intersection memory. + +Carts all move at the same speed; they take turns moving a single step at a time. They do this based +on their [1m[97mcurrent location[0m: carts on the top row move first (acting from left to right), then carts +on the second row move (again from left to right), then carts on the third row, and so on. Once +each cart has moved one step, the process repeats; each of these loops is called a +[1m[97mtick[0m. + +For example, suppose there are two carts on a straight track: + +| | | | | +v | | | | +| v v | | +| | | v X +| | ^ ^ | +^ ^ | | | +| | | | | + +First, the top cart moves. It is facing down (v), so it moves down one square. Second, the bottom +cart moves. It is facing up (^), so it moves up one square. Because all carts have moved, the first +tick ends. Then, the process repeats, starting with the first cart. The first cart moves down, +then the second cart moves up - right into the first cart, colliding with it! (The location of the +crash is marked with an X.) This ends the second and last tick. +Here is a longer example: + +/->-\ +| | /----\ +| /-+--+-\ | +| | | | v | +\-+-/ \-+--/ + \------/ + +/-->\ +| | /----\ +| /-+--+-\ | +| | | | | | +\-+-/ \->--/ + \------/ + +/---v +| | /----\ +| /-+--+-\ | +| | | | | | +\-+-/ \-+>-/ + \------/ + +/---\ +| v /----\ +| /-+--+-\ | +| | | | | | +\-+-/ \-+->/ + \------/ + +/---\ +| | /----\ +| /->--+-\ | +| | | | | | +\-+-/ \-+--^ + \------/ + +/---\ +| | /----\ +| /-+>-+-\ | +| | | | | ^ +\-+-/ \-+--/ + \------/ + +/---\ +| | /----\ +| /-+->+-\ ^ +| | | | | | +\-+-/ \-+--/ + \------/ + +/---\ +| | /----< +| /-+-->-\ | +| | | | | | +\-+-/ \-+--/ + \------/ + +/---\ +| | /---<\ +| /-+--+>\ | +| | | | | | +\-+-/ \-+--/ + \------/ + +/---\ +| | /--<-\ +| /-+--+-v | +| | | | | | +\-+-/ \-+--/ + \------/ + +/---\ +| | /-<--\ +| /-+--+-\ | +| | | | v | +\-+-/ \-+--/ + \------/ + +/---\ +| | /<---\ +| /-+--+-\ | +| | | | | | +\-+-/ \-<--/ + \------/ + +/---\ +| | v----\ +| /-+--+-\ | +| | | | | | +\-+-/ \<+--/ + \------/ + +/---\ +| | /----\ +| /-+--v-\ | +| | | | | | +\-+-/ ^-+--/ + \------/ + +/---\ +| | /----\ +| /-+--+-\ | +| | | X | | +\-+-/ \-+--/ + \------/ + +After following their respective paths for a while, the carts eventually crash.

With the current recipes' scores of 3 and 7, +their sum is 10, and so two new recipes would be created: the first with score 1 and the second with +score 0.

Looks like they're here for a fight. + +You scan the area, generating a map of the walls (#), open cavern (.), and starting position of +every Goblin (G) and Elf (E) (your puzzle input). + +Combat proceeds in [1m[97mrounds[0m; in each round, each unit that is still alive takes a [1m[97mturn[0m, resolving all +of its actions before the next unit's turn begins.

Units never move or +attack diagonally, as doing so would be dishonorable. When multiple choices are equally valid, ties +are broken in [1m[97mreading order[0m: top-to-bottom, then left-to-right. For instance, the order in which +units take their turns within a round is the [1m[97mreading order of their starting positions[0m in that +round, regardless of the type of unit or whether other units have moved after the round started. +For example: + + would take their +These units: turns in this order: + ####### ####### + #.G.E.# #.1.2.# + #E.G.E# #3.4.5# + #.G.E.# #.6.7.# + ####### ####### + +Each unit begins its turn by identifying all possible [1m[97mtargets[0m (enemy units). If no targets remain, +combat ends. + +Then, the unit identifies all of the open squares (.) that are [1m[97min range[0m of each target; these are +the squares which are [1m[97madjacent[0m (immediately up, down, left, or right) to any target and which aren't +already occupied by a wall or another unit. Alternatively, the unit might [1m[97malready[0m be in range of a +target. If the unit is not already in range of a target, and there are no open squares which are in +range of a target, the unit ends its turn. + +If the unit is already in range of a target, it does not [1m[97mmove[0m, but continues its turn with an +[1m[97mattack[0m. Otherwise, since it is not in range of a target, it [1m[97mmoves[0m. + +To [1m[97mmove[0m, the unit first considers the squares that are [1m[97min range[0m and determines [1m[97mwhich of those +squares it could reach in the fewest steps[0m. A [1m[97mstep[0m is a single movement to any [1m[97madjacent[0m (immediately +up, down, left, or right) open (.) square. Units cannot move into walls or other units. The unit +does this while considering the [1m[97mcurrent positions of units[0m and does [1m[97mnot[0m do any prediction about +where units will be later. If the unit cannot reach (find an open path to) any of the squares that +are in range, it ends its turn. If multiple squares are in range and [1m[97mtied[0m for being reachable in the +fewest steps, the square which is first in [1m[97mreading order[0m is chosen. For example: + +Targets: In range: Reachable: Nearest: Chosen: +####### ####### ####### ####### ####### +#E..G.# #E.?G?# #E.@G.# #E.!G.# #E.+G.# +#...#.# --> #.?.#?# --> #.@.#.# --> #.!.#.# --> #...#.# +#.G.#G# #?G?#G# #@G@#G# #!G.#G# #.G.#G# +####### ####### ####### ####### ####### + +In the above scenario, the Elf has three targets (the three Goblins): + + + - Each of the Goblins has open, adjacent squares which are [1m[97min range[0m (marked with a ? on the map). + + - Of those squares, four are [1m[97mreachable[0m (marked @); the other two (on the right) would require +moving through a wall or unit to reach. + + - Three of these reachable squares are [1m[97mnearest[0m, requiring the fewest steps (only 2) to reach +(marked !). + + - Of those, the square which is first in reading order is [1m[97mchosen[0m (+). + + +The unit then takes a single [1m[97mstep[0m toward the chosen square along the [1m[97mshortest path[0m to that square. +If multiple steps would put the unit equally closer to its destination, the unit chooses the step +which is first in reading order. (This requires knowing when there is [1m[97mmore than one shortest +path[0m so that you can consider the first step of each such path.) For example: + +In range: Nearest: Chosen: Distance: Step: +####### ####### ####### ####### ####### +#.E...# #.E...# #.E...# #4E[1m[97m2[0m12# #..E..# +#...?.# --> #...!.# --> #...+.# --> #3[1m[97m2[0m101# --> #.....# +#..?G?# #..!G.# #...G.# #432G2# #...G.# +####### ####### ####### ####### ####### + +The Elf sees three squares in range of a target (?), two of which are nearest (!), and so the first +in reading order is chosen (+). Under "Distance", each open square is marked with its distance from +the destination square; the two squares to which the Elf could move on this turn (down and to the +right) are both equally good moves and would leave the Elf 2 steps from being in range of the +Goblin.

If there are no such targets, the unit ends its turn. Otherwise, the adjacent target +with the [1m[97mfewest hit points[0m is selected; in a tie, the adjacent target with the fewest hit points +which is first in reading order is selected. + +The unit deals damage equal to its [1m[97mattack power[0m to the selected target, reducing its hit points by +that amount. If this reduces its hit points to 0 or fewer, the selected target [1m[97mdies[0m: its square +becomes . and it takes no further turns. + +Each [1m[97munit[0m, either Goblin or Elf, has 3 [1m[97mattack power[0m and starts with 200 [1m[97mhit points[0m. + +For example, suppose the only Elf is about to attack: + + HP: HP: +G.... 9 G.... 9 +..G.. 4 ..G.. 4 +..E[1m[97mG[0m. 2 --> ..E.. +..G.. 2 ..G.. 2 +...G. 1 ...G. 1 + +The "HP" column shows the hit points of the Goblin to the left in the corresponding row. The Elf is +in range of three targets: the Goblin above it (with 4 hit points), the Goblin to its right (with 2 +hit points), and the Goblin below it (also with 2 hit points). Because three targets are in range, +the ones with the lowest hit points are selected: the two Goblins with 2 hit points each (one to the +right of the Elf and one below the Elf). Of those, the Goblin first in reading order (the one to the +right of the Elf) is selected. The selected Goblin's hit points (2) are reduced by the Elf's attack +power (3), reducing its hit points to -1, killing it. + +After attacking, the unit's turn ends. Regardless of how the unit's turn ends, the next unit in the +round takes its turn. If all units have taken turns in this round, the round ends, and a new round +begins. + +The Elves look quite outnumbered.

You have a little while before you reach your next destination, and with a bit of trial +and error, you manage to pull up a programming manual on the device's tiny screen. + +According to the manual, the device has four registers (numbered 0 through 3) that can be +manipulated by instructions containing one of 16 opcodes. The registers start with the value 0. + +Every instruction consists of four values: an [1m[97mopcode[0m, two [1m[97minputs[0m (named A and B), and an +[1m[97moutput[0m (named C), in that order. The opcode specifies the behavior of the instruction and how the +inputs are interpreted. The output, C, is always treated as a register. + +In the opcode descriptions below, if something says "[1m[97mvalue A[0m", it means to take the number given as +A [1m[97mliterally[0m. (This is also called an "immediate" value.) If something says "[1m[97mregister A[0m", it means to +use the number given as A to read from (or write to) the [1m[97mregister with that number[0m. So, if the +opcode addi adds register A and value B, storing the result in register C, and the instruction addi +0 7 3 is encountered, it would add 7 to the value contained by register 0 and store the sum in +register 3, never modifying registers 0, 1, or 2 in the process. + +Many opcodes are similar except for how they interpret their arguments. The opcodes fall into seven +general categories: + +Addition: + + + - addr (add register) stores into register C the result of adding register A and register B. + + - addi (add immediate) stores into register C the result of adding register A and value B. + + +Multiplication: + + + - mulr (multiply register) stores into register C the result of multiplying register A and register +B. + + - muli (multiply immediate) stores into register C the result of multiplying register A and value +B. + + +Bitwise AND: + + + - banr (bitwise AND register) stores into register C the result of the bitwise AND of register A +and register B. + + - bani (bitwise AND immediate) stores into register C the result of the bitwise AND of register A +and value B. + + +Bitwise OR: + + + - borr (bitwise OR register) stores into register C the result of the bitwise OR of register A and +register B. + + - bori (bitwise OR immediate) stores into register C the result of the bitwise OR of register A and +value B. + + +Assignment: + + + - setr (set register) copies the contents of register A into register C. (Input B is ignored.) + + - seti (set immediate) stores value A into register C. (Input B is ignored.) + + +Greater-than testing: + + + - gtir (greater-than immediate/register) sets register C to 1 if value A is greater than register +B. Otherwise, register C is set to 0. + + - gtri (greater-than register/immediate) sets register C to 1 if register A is greater than value +B. Otherwise, register C is set to 0. + + - gtrr (greater-than register/register) sets register C to 1 if register A is greater than register +B. Otherwise, register C is set to 0. + + +Equality testing: + + + - eqir (equal immediate/register) sets register C to 1 if value A is equal to register B. +Otherwise, register C is set to 0. + + - eqri (equal register/immediate) sets register C to 1 if register A is equal to value B. +Otherwise, register C is set to 0. + + - eqrr (equal register/register) sets register C to 1 if register A is equal to register B. +Otherwise, register C is set to 0. + + +Unfortunately, while the manual gives the [1m[97mname[0m of each opcode, it doesn't seem to indicate the +[1m[97mnumber[0m. However, you can monitor the CPU to see the contents of the registers before and after +instructions are executed to try to work them out. Each opcode has a number from 0 through 15, but +the manual doesn't say which is which. For example, suppose you capture the following sample: + +Before: [3, 2, 1, 1] +9 2 1 2 +After: [3, 2, 2, 1] + +This sample shows the effect of the instruction 9 2 1 2 on the registers. Before the instruction is +executed, register 0 has value 3, register 1 has value 2, and registers 2 and 3 have value 1. After +the instruction is executed, register 2's value becomes 2. + +The instruction itself, 9 2 1 2, means that opcode 9 was executed with A=2, B=1, and C=2. Opcode 9 +could be any of the 16 opcodes listed above, but only three of them behave in a way that would cause +the result shown in the sample: + + + - Opcode 9 could be mulr: register 2 (which has a value of 1) times register 1 (which has a value +of 2) produces 2, which matches the value stored in the output register, register 2. + + - Opcode 9 could be addi: register 2 (which has a value of 1) plus value 1 produces 2, which +matches the value stored in the output register, register 2. + + - Opcode 9 could be seti: value 2 matches the value stored in the output register, register 2; the +number given for B is irrelevant. + + +None of the other opcodes produce the result captured in the sample. Because of this, the sample +above [1m[97mbehaves like three opcodes[0m. + +You collect many of these samples (the first section of your puzzle input).

The vacuum robot can +do this automatically if it gets into range of a robot.

The main routine may only call the +[1m[97mmovement functions[0m: A, B, or C. Supply the movement functions to use as ASCII text, separating them +with commas (,, ASCII code 44), and ending the list with a newline (ASCII code 10).

Movement functions may use L to [1m[97mturn +left[0m, R to [1m[97mturn right[0m, or a number to [1m[97mmove forward[0m that many units. Movement functions may not call +other movement functions. Again, separate the actions with commas and end the list with a newline. +For example, to move forward 10 units, turn left, move forward 8 units, turn right, and finally move +forward 6 units, provide the string 10,L,8,R,6 and then a newline. + +Finally, you will be asked whether you want to see a [1m[97mcontinuous video feed[0m; provide either y or n +and a newline.

The device's manual goes on to explain: + +"In programs where flow control is required, the instruction pointer can be [1m[97mbound to a register[0m so +that it can be manipulated directly. This way, setr/seti can function as absolute jumps, addr/addi +can function as relative jumps, and other opcodes can cause truly fascinating effects." + +This mechanism is achieved through a declaration like #ip 1, which would modify register 1 so that +accesses to it let the program indirectly access the instruction pointer itself. To compensate for +this kind of binding, there are now [1m[97msix[0m registers (numbered 0 through 5); the five not bound to the +instruction pointer behave as normal. Otherwise, the same rules apply as the last time you worked +with this device. + +When the [1m[97minstruction pointer[0m is bound to a register, its value is written to that register just +before each instruction is executed, and the value of that register is written back to the +instruction pointer immediately after each instruction finishes execution. Afterward, move to the +next instruction by adding one to the instruction pointer, even if the value in the instruction +pointer was just updated by an instruction. (Because of this, instructions must effectively set the +instruction pointer to the instruction [1m[97mbefore[0m the one they want executed next.) + +The instruction pointer is 0 during the first instruction, 1 during the second, and so on. If the +instruction pointer ever causes the device to attempt to load an instruction outside the +instructions defined in the program, the program instead immediately halts. The instruction pointer +starts at 0. + +It turns out that this new information is already proving useful: the CPU in the device is not very +powerful, and a background process is occupying most of its time. You dump the background process' +declarations and instructions to a file (your puzzle input), making sure to use the names of the +opcodes rather than the numbers. + +For example, suppose you have the following program: + +#ip 0 +seti 5 0 1 +seti 6 0 2 +addi 0 1 0 +addr 1 2 3 +setr 1 0 0 +seti 8 0 4 +seti 9 0 5 + +When executed, the following instructions are executed.

This is not an instruction, and so the value of the instruction pointer does not +change during the processing of this line. + + - The instruction pointer contains 0, and so the first instruction is executed (seti 5 0 1). It +updates register 0 to the current instruction pointer value (0), sets register 1 to 5, sets the +instruction pointer to the value of register 0 (which has no effect, as the instruction did not +modify register 0), and then adds one to the instruction pointer. + + - The instruction pointer contains 1, and so the second instruction, seti 6 0 2, is executed. This +is very similar to the instruction before it: 6 is stored in register 2, and the instruction pointer +is left with the value 2. + + - The instruction pointer is 2, which points at the instruction addi 0 1 0. This is like a +[1m[97mrelative jump[0m: the value of the instruction pointer, 2, is loaded into register 0. Then, addi finds +the result of adding the value in register 0 and the value 1, storing the result, 3, back in +register 0. Register 0 is then copied back to the instruction pointer, which will cause it to end up +1 larger than it would have otherwise and skip the next instruction (addr 1 2 3) entirely. Finally, +1 is added to the instruction pointer. + + - The instruction pointer is 4, so the instruction setr 1 0 0 is run.

"I don't have time to draw +out a map of this place - it's [1m[97mhuge[0m. Instead, I can give you directions to [1m[97mevery room in the +facility[0m!" He writes down some directions on a piece of parchment and runs off. In the example +above, the instructions might have been ^WNE$, a regular expression or "[1m[97mregex[0m" (your puzzle input). + +The regex matches routes (like WNE for "west, north, east") that will take you from your current +room through various doors in the facility. In aggregate, the routes will take you through +[1m[97mevery door in the facility at least once[0m; mapping out all of these routes will let you build a +proper map and find your way around. + +^ and $ are at the beginning and end of your regex; these just mean that the regex doesn't match +anything outside the routes it describes. (Specifically, ^ matches the start of the route, and $ +matches the end of it.) These characters will not appear elsewhere in the regex. + +The rest of the regex matches various sequences of the characters N (north), S (south), E (east), +and W (west). In the example above, ^WNE$ matches only one route, WNE, which means you can move +[1m[97mwest, then north, then east[0m from your current position. Sequences of letters like this always match +that exact route in the same order. + +Sometimes, the route can [1m[97mbranch[0m. A branch is given by a [1m[97mlist of options[0m separated by pipes (|) and +wrapped in parentheses. So, ^N(E|W)N$ contains a branch: after going north, you must choose to go +[1m[97meither east or west[0m before finishing your route by going north again. By tracing out the possible +routes after branching, you can determine where the doors are and, therefore, where the rooms are in +the facility. + +For example, consider this regex: ^ENWWW(NEEE|SSE(EE|N))$ + +This regex begins with ENWWW, which means that from your current position, all routes must begin by +moving east, north, and then west three times, in that order. After this, there is a branch. Before +you consider the branch, this is what you know about the map so far, with doors you aren't sure +about marked with a ?: + +#?#?#?#?# +?.|.|.|.? +#?#?#?#-# + ?X|.? + #?#?# + +After this point, there is (NEEE|SSE(EE|N)). This gives you exactly two options: NEEE and SSE(EE|N). +By following NEEE, the map now looks like this: + +#?#?#?#?# +?.|.|.|.? +#-#?#?#?# +?.|.|.|.? +#?#?#?#-# + ?X|.? + #?#?# + +Now, only SSE(EE|N) remains. Because it is in the same parenthesized group as NEEE, it starts from +the same room NEEE started in. It states that starting from that point, there exist doors which will +allow you to move south twice, then east; this ends up at another branch. After that, you can either +move east twice or north once. This information fills in the rest of the doors: + +#?#?#?#?# +?.|.|.|.? +#-#?#?#?# +?.|.|.|.? +#-#?#?#-# +?.?.?X|.? +#-#-#?#?# +?.|.|.|.? +#?#?#?#?# + +Once you've followed all possible routes, you know the remaining unknown parts are all walls, +producing a finished map of the facility: + +######### +#.|.|.|.# +#-####### +#.|.|.|.# +#-#####-# +#.#.#X|.# +#-#-##### +#.|.|.|.# +######### + +Sometimes, a list of options can have an [1m[97mempty option[0m, like (NEWS|WNSE|). This means that routes at +this point could effectively skip the options in parentheses and move on immediately. For example, +consider this regex and the corresponding map: + +^ENNWSWW(NEWS|)SSSEEN(WNSE|)EE(SWEN|)NNN$ + +########### +#.|.#.|.#.# +#-###-#-#-# +#.|.|.#.#.# +#-#####-#-# +#.#.#X|.#.# +#-#-#####-# +#.#.|.|.|.# +#-###-###-# +#.|.|.#.|.# +########### + +This regex has one main route which, at three locations, can optionally include additional detours +and be valid: (NEWS|), (WNSE|), and (SWEN|). Regardless of which option is taken, the route +continues from the position it is left at after taking those steps. So, for example, this regex +matches all of the following routes (and more that aren't listed here): + + + - ENNWSWWSSSEENEENNN + + - ENNWSWW[1m[97mNEWS[0mSSSEENEENNN + + - ENNWSWW[1m[97mNEWS[0mSSSEENEE[1m[97mSWEN[0mNNN + + - ENNWSWWSSSEEN[1m[97mWNSE[0mEENNN + + +By following the various routes the regex matches, a full map of all of the doors and rooms in the +facility can be assembled. + +To get a sense for the size of this facility, you'd like to determine which room is +[1m[97mfurthest[0m from you: specifically, you would like to find the room for which the [1m[97mshortest path to that +room would require passing through the most doors[0m. + + + - In the first example (^WNE$), this would be the north-east corner [1m[97m3[0m doors away. + + - In the second example (^ENWWW(NEEE|SSE(EE|N))$), this would be the south-east corner +[1m[97m10[0m doors away. + + - In the third example (^ENNWSWW(NEWS|)SSSEEN(WNSE|)EE(SWEN|)NNN$), this would be the north-east +corner [1m[97m18[0m doors away. + + +Here are a few more examples: + +Regex: ^ESSWWN(E|NNENN(EESS(WNSE|)SSS|WWWSSSSE(SW|NNNE)))$ +Furthest room requires passing 23 doors + +############# +#.|.|.|.|.|.# +#-#####-###-# +#.#.|.#.#.#.# +#-#-###-#-#-# +#.#.#.|.#.|.# +#-#-#-#####-# +#.#.#.#X|.#.# +#-#-#-###-#-# +#.|.#.|.#.#.# +###-#-###-#-# +#.|.#.|.|.#.# +############# + +Regex: ^WSSEESWWWNW(S|NENNEEEENN(ESSSSW(NWSW|SSEN)|WSWWN(E|WWS(E|SS))))$ +Furthest room requires passing 31 doors + +############### +#.|.|.|.#.|.|.# +#-###-###-#-#-# +#.|.#.|.|.#.#.# +#-#########-#-# +#.#.|.|.|.|.#.# +#-#-#########-# +#.#.#.|X#.|.#.# +###-#-###-#-#-# +#.|.#.#.|.#.|.# +#-###-#####-### +#.|.#.|.|.#.#.# +#-#-#####-#-#-# +#.#.|.|.|.#.|.# +############### + +[1m[97mWhat is the largest number of doors you would be required to pass through to reach a room?[0m That is, +find the room for which the shortest path from your starting location to that room would require +passing through the most doors; what is the fewest doors you can pass through to reach it? + + diff --git a/src/20/part2 b/src/20/part2 new file mode 100644 index 0000000..bef65a3 --- /dev/null +++ b/src/20/part2 @@ -0,0 +1,207 @@ +--- Part Two --- + +Strangely, the exit isn't open when you reach it.

It's snowing and dark outside; the only light you can +see is coming from a small cottage in the distance. You make your way there and knock on the door. + +A portly man with a large, white beard answers the door and invites you inside. For someone living +near the North Pole in -483, he must not get many visitors, but he doesn't act surprised to see you. +Instead, he offers you some milk and cookies. + +After talking for a while, he asks a favor of you. His friend hasn't come back in a few hours, and +he's not sure where he is. Scanning the region briefly, you discover one life signal in a cave +system nearby; his friend must have taken shelter there. The man asks if you can go there to +retrieve his friend. + +The cave is divided into square [1m[97mregions[0m which are either dominantly [1m[97mrocky[0m, [1m[97mnarrow[0m, or +[1m[97mwet[0m (called its [1m[97mtype[0m). Each region occupies exactly one [1m[97mcoordinate[0m in X,Y format where X and Y are +integers and zero or greater. (Adjacent regions can be the same type.) + +The scan (your puzzle input) is not very detailed: it only reveals the [1m[97mdepth[0m of the cave system and +the [1m[97mcoordinates of the target[0m. However, it does not reveal the type of each region. The mouth of the +cave is at 0,0. + +The man explains that due to the unusual geology in the area, there is a method to determine any +region's type based on its [1m[97merosion level[0m. The erosion level of a region can be determined from its +[1m[97mgeologic index[0m. The geologic index can be determined using the first rule that applies from the list +below: + + + - The region at 0,0 (the mouth of the cave) has a geologic index of 0. + + - The region at the coordinates of the target has a geologic index of 0. + + - If the region's Y coordinate is 0, the geologic index is its X coordinate times 16807. + + - If the region's X coordinate is 0, the geologic index is its Y coordinate times 48271. + + - Otherwise, the region's geologic index is the result of multiplying the erosion +[1m[97mlevels[0m of the regions at X-1,Y and X,Y-1. + + +A region's [1m[97merosion level[0m is its [1m[97mgeologic index[0m plus the cave system's [1m[97mdepth[0m, all modulo 20183. Then: + + + - If the [1m[97merosion level modulo 3[0m is 0, the region's type is [1m[97mrocky[0m. + + - If the [1m[97merosion level modulo 3[0m is 1, the region's type is [1m[97mwet[0m. + + - If the [1m[97merosion level modulo 3[0m is 2, the region's type is [1m[97mnarrow[0m. + + +For example, suppose the cave system's depth is 510 and the target's coordinates are 10,10. Using % +to represent the modulo operator, the cavern would look as follows: + + + - At 0,0, the geologic index is 0. The erosion level is (0 + 510) % 20183 = 510. The type is 510 % +3 = 0, [1m[97mrocky[0m. + + - At 1,0, because the Y coordinate is 0, the geologic index is 1 * 16807 = 16807. The erosion level +is (16807 + 510) % 20183 = 17317. The type is 17317 % 3 = 1, [1m[97mwet[0m. + + - At 0,1, because the X coordinate is 0, the geologic index is 1 * 48271 = 48271. The erosion +level is (48271 + 510) % 20183 = 8415. The type is 8415 % 3 = 0, [1m[97mrocky[0m. + + - At 1,1, neither coordinate is 0 and it is not the coordinate of the target, so the geologic index +is the erosion level of 0,1 (8415) times the erosion level of 1,0 (17317), 8415 * 17317 = 145722555. +The erosion level is (145722555 + 510) % 20183 = 1805.

He seems relieved to see his +friend, but quickly notices that the little reindeer caught some kind of cold while out exploring. + +The portly man explains that this reindeer's immune system isn't similar to regular reindeer immune +systems: + +The [1m[97mimmune system[0m and the [1m[97minfection[0m each have an army made up of several [1m[97mgroups[0m; each +[1m[97mgroup[0m consists of one or more identical [1m[97munits[0m.

Here is an example group: + +18 units each with 729 hit points (weak to fire; immune to cold, slashing) + with an attack that does 8 radiation damage at initiative 10 + +Each group also has an [1m[97meffective power[0m: the number of units in that group multiplied by their attack +damage. The above group has an effective power of 18 * 8 = 144. Groups never have zero or negative +units; instead, the group is removed from combat. + +Each [1m[97mfight[0m consists of two phases: [1m[97mtarget selection[0m and [1m[97mattacking[0m. + +During the [1m[97mtarget selection[0m phase, each group attempts to choose one target. In decreasing order of +effective power, groups choose their targets; in a tie, the group with the higher initiative chooses +first. The attacking group chooses to target the group in the enemy army to which it would deal the +most damage (after accounting for weaknesses and immunities, but not accounting for whether the +defending group has enough units to actually receive all of that damage). + +If an attacking group is considering two defending groups to which it would deal equal damage, it +chooses to target the defending group with the largest effective power; if there is still a tie, it +chooses the defending group with the highest initiative. If it cannot deal any defending groups +damage, it does not choose a target. Defending groups can only be chosen as a target by one +attacking group. + +At the end of the target selection phase, each group has selected zero or one groups to attack, and +each group is being attacked by zero or one groups. + +During the [1m[97mattacking[0m phase, each group deals damage to the target it selected, if any. Groups attack +in decreasing order of initiative, regardless of whether they are part of the infection or the +immune system. (If a group contains no units, it cannot attack.) + +The damage an attacking group deals to a defending group depends on the attacking group's attack +type and the defending group's immunities and weaknesses. By default, an attacking group would deal +damage equal to its [1m[97meffective power[0m to the defending group. However, if the defending group is +[1m[97mimmune[0m to the attacking group's attack type, the defending group instead takes [1m[97mno damage[0m; if the +defending group is [1m[97mweak[0m to the attacking group's attack type, the defending group instead takes +[1m[97mdouble damage[0m. + +The defending group only loses [1m[97mwhole units[0m from damage; damage is always dealt in such a way that it +kills the most units possible, and any remaining damage to a unit that does not immediately kill it +is ignored. For example, if a defending group contains 10 units with 10 hit points each and receives +75 damage, it loses exactly 7 units and is left with 3 units at full health. + +After the fight is over, if both armies still contain units, a new fight begins;
