Solution: Shortest Common Supersequence

Explore the dynamic programming approach to find the shortest common supersequence of two strings. Understand how to use the longest common subsequence table to efficiently build the shortest string containing both as subsequences, optimizing order and minimizing length.

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 ...
