Python
Nobody posted a solution in python for today???
Here is my solver with a little extra to print the Part 2 path. you can totally remove/comment out the printing out of the part 2 path, but it is neat to look at!
Execution time: ~25 milliseconds + an unnecessary ~7 ms to print part 2 path
[ Paste ]
This is the one where you don't have it print out the Part 2 path and smaller: [ Paste ]
here is also a faster version that uses binary search instead. but its only a few milliseconds faster.
Execution time: ~21 milliseconds + an unnecessary ~7 ms to print part 2 path
