    Hi,

    Most of the peope solved this problem but time complexity of solution is O(n*m) (due to two nested for loops)which can not be used to solve this problem for given time constraint, so you need better approach which beats O(n*m)

    I have created a video tutorial for you and uploaded the same on youtube with complete explanation along with code complexity analysis.

    Here is the video tutorial for my solution O(n+m) complexity passed all test cases.

    Would really appreciate your feedback like, dislike , comment etc. on my video.
