Shortest Common Supersequence - Given two strings str1 and str2, return the shortest string that has both str1 and str2 as subsequences. If there are multiple valid strings, return any of them.

Nov 8, 2025 · Our goal is to build the shortest string that contains both s1 and s2 as subsequences. A naive thought might be to simply merge all characters of both strings - but that actually gives the …

A shortest common supersequence (SCS) is a common supersequence of minimal length. In the SCS problem, two sequences X and Y are given, and the task is to find a shortest possible common …

In-depth solution and explanation for LeetCode 1092. Shortest Common Supersequence in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official …

A supersequence must contain both strings as subsequences. The shortest one minimizes redundancy by sharing as many characters as possible between the two strings. This is directly related to the …

Reconstruct the shortest common supersequence by traversing the two strings in parallel and using the LCS as a guide. For every character in the LCS, append all non-LCS characters from str1 and str2 …

The shortest common supersequence is the smallest string that has both input strings as subsequences. Think of it as merging two strings optimally while preserving their character order. Example: For …
