### Longest Common Subsequence

##### Given two sequences, find the length of longest subsequence present in both of them. A subsequence is a sequence that appears in the same relative order, but not necessarily contiguous.

For example, “abc”, “abg”, “bdf”, “aeg”, ‘”acefg”, .. etc are subsequences of “abcdefg”. So a string of length n has 2^n different possible subsequences.

**Output:**

String 1 : ABCBDAD String 2 : BDCABA LCA : 4 LCA (using dynamic programming ): BCBA
