Solution: Shortest Common Supersequence

Explore how to find the shortest common supersequence of two strings by leveraging dynamic programming and the longest common subsequence concept. Learn to build a DP table to efficiently reconstruct the shortest string containing both inputs as subsequences. Understand the time and space complexities involved in the solution.

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 ...
