📘 Welcome to Part 209 of Code & Debug’s DSA in Python Course!

In this video, we go beyond LCS length and actually print one Longest Common Subsequence between two strings. The strategy is in two clean phases: first, we build the classic LCS DP table of lengths; then we backtrack from the bottom-right to reconstruct a valid LCS by following matches and choosing the direction of larger subproblems when characters don’t match. This approach is robust, interview-ready, and easy to code.
