part2 (1812B)
1--- Part Two --- 2 3Based on your calculations, the planned course doesn't seem to make any sense. You find the 4submarine manual and discover that the process is actually slightly more complicated. 5 6In addition to horizontal position and depth, you'll also need to track a third value, 7[1m[37maim[0m, which also starts at 0. The commands also mean something entirely different than 8you first thought: 9 10 11 - down X [1m[37mincreases[0m your aim by X units. 12 13 - up X [1m[37mdecreases[0m your aim by X units. 14 15 - forward X does two things: 16 - It increases your horizontal position by X units. 17 18 - It increases your depth by your aim [1m[37mmultiplied by[0m X. 19 20 21 22 23Again note that since you're on a submarine, down and up do the opposite of what you might expect: 24"down" means aiming in the positive direction. 25 26Now, the above example does something different: 27 28 29 - forward 5 adds 5 to your horizontal position, a total of 5. Because your aim is 0, your depth 30does not change. 31 32 - down 5 adds 5 to your aim, resulting in a value of 5. 33 34 - forward 8 adds 8 to your horizontal position, a total of 13. Because your aim is 5, your depth 35increases by 8*5=40. 36 37 - up 3 decreases your aim by 3, resulting in a value of 2. 38 39 - down 8 adds 8 to your aim, resulting in a value of 10. 40 41 - forward 2 adds 2 to your horizontal position, a total of 15. Because your aim is 10, your depth 42increases by 2*10=20 to a total of 60. 43 44 45After following these new instructions, you would have a horizontal position of 15 and a depth of 4660. (Multiplying these produces [1m[37m900[0m.) 47 48Using this new interpretation of the commands, calculate the horizontal position and depth you would 49have after following the planned course. [1m[37mWhat do you get if you multiply your final 50horizontal position by your final depth?[0m 51 52
