Two Strings is a programming challenge on HackerRank. You are given with two strings, determine if they share a common sub-string. A substring may be as small as just one character.
Watch the video to understand the problem in a simplified manner. I then work along with you to solve it first using a Brute Force approach, and then an efficient approach. All along with visuals and explanations.
