Answer:
Explanation:
The following code is written in Java and creates the recursive function to find the longest common substring as requested.
static int lengthOfLongestSubsequence(String X, String Y) {
int m = X.length();
int n = Y.length();
if (m == 0 || n == 0) {
return 0;
}
if (X.charAt(m - 1) == Y.charAt(n - 1)) {
return 1 + lengthOfLongestSubsequence(X, Y);
} else {
return Math.max(lengthOfLongestSubsequence(X, Y),
lengthOfLongestSubsequence(X, Y));
}
}
It takes a lot of time and effort to write the code for the same. It is very complex and difficult to understand. The syntax is difficult to remember. It has a lack of portability of program between different computer architectures.
Hope that helps
