The problem is it won't run. It was written in google docs without IDE. Everyone who programmed in their lives knows this. You cannot write out a whole algorithm like that and not make any even trivial error. This is like writing code in notepad and creating a PR without building or running it to test once. What is this testing? There is no real world scenario where you are expected to work like this and for a good reason.
