Didn't understand the part of the pigeon hole principle. - how did you use it ? Can you explain it in somewhat easy way.

Pigeon hole principle says that if there are N numbers and we are taking N+1 numbers then at least one number bound to get repeated. Similar concept here, let say if the N+M-1 cells are from the same row and same column of the current cell and we take N+M+1 max cells then we are going to find the max and second max excluding all the cells of the current cell's row and column If you find this helpful, please like and subscribe
