Solution: Shortest Common Supersequence

Understand how to solve the shortest common supersequence problem by applying dynamic programming concepts and leveraging the longest common subsequence. This lesson guides you through building a solution that efficiently combines two strings while preserving character order, preparing you for coding interviews.

We'll cover the following...

Statement

You are given two strings, str1 and str2. Your task is to find the shortest common supersequence (SCS). The shortest possible string that contains both str1 and str2 as subsequences.

If multiple strings satisfy this condition, you may return any one of them.

Note: A string ss is considered a subsequence of another string tt if ss can be obtained by deleting zero or more characters from tt without changing the order ...
