Number of moves it has taken you to get to a certain square matters, but you don't take it into account.
why it matter?
Just try to simulate your code's behaviour on the test number 45. You'll move in a snake pattern and you'll close your way to the last column.
why in my code "just" move like snake ?
I have 2 loops! but it doesn't work well!
