Hi everyone, welcome to my channel where I upload the video solutions to the "Problem of the day" that is asked daily on GeeksforGeeks. Today's problem is "Largest rectangular sub-matrix whose sum is 0" which is a hard level question.
In this video, I will explain a solution involving the concepts of prefix sum to solve this problem which is both time efficient, O((N*M)^2), where N is the number of rows and M is the number of columns and space efficient, O(N*M).
