Hello coders,\n\nI had a question in my interview and I can\'t think of a stright solution. Question goes like this:\nI have a 2D matrix of 0 and 1\nOnly operation allowed is to either flip whole row or columns element ( by flipping each elements from 0 to 1 or from 1 to 0). For Example: [1 0 1] -> [0 1 0]\nQuestion - Find an algorithm to determine if a zero matric can be obtained by any number of rows or column operations ?\n\nI\'m so stuck on this one. Any help ?
