--- Day 2: Dive! ---
Now, you need to figure out how to pilot this thing.
It seems like the submarine can take a series of commands like forward 1, down 2, or up 3:
- forward X increases the horizontal position by X units.
- down X [1m[37mincreases[0m the depth by X units.
- up X [1m[37mdecreases[0m the depth by X units.
Note that since you're on a submarine, down and up affect your [1m[37mdepth[0m, and so they have
the opposite result of what you might expect.
The submarine seems to already have a planned course (your puzzle input). You should probably figure
out where it's going. For example:
forward 5
down 5
forward 8
up 3
down 8
forward 2
Your horizontal position and depth both start at 0. The steps above would then modify them as
follows:
- forward 5 adds 5 to your horizontal position, a total of 5.
- down 5 adds 5 to your depth, resulting in a value of 5.
- forward 8 adds 8 to your horizontal position, a total of 13.
- up 3 decreases your depth by 3, resulting in a value of 2.
- down 8 adds 8 to your depth, resulting in a value of 10.
- forward 2 adds 2 to your horizontal position, a total of 15.
After following these instructions, you would have a horizontal position of 15 and a depth of 10.
(Multiplying these together produces [1m[37m150[0m.)
Calculate the horizontal position and depth you would have after following the planned course.
[1m[37mWhat do you get if you multiply your final horizontal position by your final depth?[0m
