The score of re-submit of the leading solution(score is 8) is 54, Why? The codycomputer slows down?

@Athi, your solution contains many "magic" constant variables that I don't know how you got. William's solution is much easier to understood, although it is slower than yours.

@goc3 A piece of advice, measure the running time(using tic, toc, for example) in the test suit to see which solution is fast.

@ Tim Well done, Tim. I noticed the bug of my solution, but it did work for the old test suit, and I was too lazy to fix the bug.
