There is a 2D matrix which has 0s and 1s . Your main aim is to tell maximum number of rows that are max amplified . A row is max amplified if all the columns in a row are 1. You have been given K which tells the number of column inversions you HAVE to do . Column inversion means that the whole column of that 2D matrix is inverted . 0 is replaced by 1 and 1 is replaced by 0 . You have to tell that after K inversions how many rows of max amplification will be present . K inversions gave to take place . Not less than that not more . One column can be inverted more than once .
