Today's problem is "Find duplicate rows in a binary matrix" which is a medium level question and has been asked by Microsoft. In this video, I will explain an optimised solution using bits and an unordered set to solve this problem which is both time efficient, O(N*M), and space efficient, O(M). 00:00 Introduction to the problem 03:23 Understanding the problem 04:03 Framing the Brute force approach 05:48 Framing the optimal approach 09:33 Going through the code I hope you enjoyed this video and learned something new. If you did, please give it a thumbs up 👍 and share it with your friends who are also interested in coding.
