Intuition: To find the longest common subsequence between two strings, we can use dynamic programming. The problem can be broken down into smaller subproblems by considering different suffixes of the ...

Let the `dp[i][j]` be the length of the longest common subsequence of prefixes `S[1..i]` and `T[1..j]`. Our answer (the length of LCS) is `dp[|S|][|T|]` since the prefix of the length of string is the ...
