The length of the longest common subsequence between s1 and s2 is ____.

Explanation:

The length of the longest common subsequence between two strings s1 and s2 can be calculated using dynamic programming.

By filling in a 2D matrix with the lengths of common subsequences for different prefixes of the two strings, we can find the length of the longest common subsequence.

The value at the bottom-right corner of the matrix represents the length of the longest common subsequence between s1 and s2.

Example:

1String s1 = "algorithm";
2String s2 = "rhythm";
3
4int longestLength = longestCommonSubsequence(s1, s2);
5System.out.println("The length of the longest common subsequence is: " + longestLength);

In this example, we have two strings s1 and s2, and we calculate the length of the longest common subsequence between them using the longestCommonSubsequence method.
