Solution: Shortest Common Supersequence

Explore how to solve the shortest common supersequence problem by applying dynamic programming techniques. Understand how the longest common subsequence informs the construction of the shortest supersequence, and learn to implement the solution using a DP table and backtracking to build the sequence efficiently.

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 ...
