DSA in Python - Longest Common Substring | DP on Strings (Tabulation + Space Opt) | Part 210 [Hindi]
📘 Welcome to Part 210 of Code & Debug’s DSA in Python Course!
Today we tackle the classic string DP: Longest Common Substring. Unlike subsequence, substring requires contiguity, so any mismatch resets the running length. We’ll solve it using bottom-up DP and then optimize space to linear, while tracking the maximum length on the fly.
