You are given a matrix having 0s & 1s where each row & column is sorted also. So need to find the maximum matrix of 1s. e.g. Below is the given matrix, note each row & column is sorted. {0,0,0,0,1} {0,0,0,1,1} {0,1,1,1,1} {0,1,1,1,1} {1,1,1,1,1} so max matrix having 1s can be- 1,1,1,1 1,1,1,1 1,1,1,1
