At first, I gave him Brute Force Approach then he asked me if I can further optimize. Then I explained to him the efficient approach which is Sliding Window Approach. He asked me to code and gave me some test cases to run. He was satisfied with the answer and asked me the time complexity which is O(n) where n is the length of the parent string. He then proceeded with the next question.

2. https://www.geeksforgeeks.org/merge-sort/
