Sorry, the logic of what the problem suggests is not very clear to me. Should the input 2D matrix be broken up in 2-by-2 matrices first, and why?
@Bainhome, I believe your code cannot perform an adaptive zigzag scan of a valid 2x2 matrix due to the conditional statement implemented.
S**t, a euqal sign is forgotten...THX buddy.
What this code done to the index by using union is well-considered. Nice!
