--- Part Two ---
Now that you know how to find low-risk paths in the cave, you can try to find your way out.
The entire cave is actually [1m[97mfive times larger in both dimensions[0m than you thought; the area you
originally scanned is just one tile in a 5x5 tile area that forms the full map. Your original map
tile repeats to the right and downward; each time the tile repeats to the right or downward, all of
its risk levels [1m[97mare 1 higher[0m than the tile immediately up or left of it. However, risk levels above
9 wrap back around to 1. So, if your original map had some position with a risk level of 8, then
that same position on each of the 25 total tiles would be as follows:
8 9 1 2 3
9 1 2 3 4
1 2 3 4 5
2 3 4 5 6
3 4 5 6 7
Each single digit above corresponds to the example position with a value of 8 on the top-left tile.
Because the full map is actually five times larger in both dimensions, that position appears a total
of 25 times, once in each duplicated tile, with the values shown above.
Here is the full five-times-as-large version of the first example above, with the original map in
the top left corner highlighted:
