Longest Common Subsequence C Program


C Program To Print Longest Common Subsequence

Let us learn how to implement Longest Common Subsequence Problem in C programming. The C program to find the longest subsequence in two strings (sequences) can be implemented using Dynamic Programming and Recursion.

What is Longest Common Sub-Sequence Problem?

In this algorithm, from a given set of strings, we have to find the longest sequence of the characters that is present in the strings.


In other words, the LCS problem is to find the longest subsequence common to all the given subsequences.

Here is the mathematical function for Longest Common Sequence Problem.

LCS Problem Algorithm Function


First Sequence: MNOPQRS

Second Sequence: MNQSTXYZ

Longest Common Subsequence: MNQS

Length: 4

Method 1: C Program To Implement LCS Problem without Recursion

Method 2: C Program To Print Length Longest Common Subsequence using Recursion
