## How do you find the longest common subsequence in Java?

Using Recursive Implementation

- // import required classes and packages.
- import java.util.*;
- import java.io.*;
- import java.util.Scanner;
- // create LCSExample2 class to find the length of the Longest Common Subsequence.
- public class LCSExample2 {
- // create getLengthOfLCS() method that returns length of the LCS.

**How do you find the LCS of a 3 string guitar?**

Input : str1 = “geeks” str2 = “geeksfor” str3 = “geeksforgeeks” Output : 5 Longest common subsequence is “geeks” i.e., length = 5 Input : str1 = “abcd1e2” str2 = “bc12ea” str3 = “bd1ea” Output : 3 Longest common subsequence is “b1e” i.e. length = 3.

**Which of the following is the longest common subsequence between the strings Abcdgh and Aedfhr?**

algorithm Dynamic Programming Longest Common Subsequence If we are given with the two strings we have to find the longest common sub-sequence present in both of them. LCS for input Sequences “ABCDGH” and “AEDFHR” is “ADH” of length 3.

### What is the time complexity of the longest common subsequence?

The general algorithms which are followed to solve the Longest Common Subsequence (LCS) problems have both time complexity and space complexity of O(m * n). To reduce this complexity, two ways are proposed in this work.

**What is the length of the longest common subsequence of strings str1 and str2?**

LCS(m,n) is length of longest common subsequence of str1 and str2. start comparing strings from their right end. if m or n is 0, return 0. if str1[m-1] == str2[n-1] (if end characters match) , return 1+LCS(m-1,n-1).

**How do you print the shortest common Supersequence?**

If the characters corresponding to current cell (i, j) in X and Y are same, then the character is part of shortest supersequence. We append it in output string and move diagonally to next cell (i.e. (i – 1, j – 1)). 2.

## Which of the following is the longest common subsequence?

Explanation: The longest common subsequence is “PRTPQRS” and its length is 7. 3. Which of the following problems can be solved using the longest subsequence problem?

**What is the length of the longest common subsequence of Aggtab and Gxtxayb?**

4

LCS for input Sequences “ABCDGH” and “AEDFHR” is “ADH” of length 3. LCS for input Sequences “AGGTAB” and “GXTXAYB” is “GTAB” of length 4.

**How do you find the longest common prefix in C?**

How to find the longest common prefix in an array of strings

- Sort the array of strings in alphabetical order.
- Compare the characters in the first and last strings in the array. Since the array is sorted, common characters among the first and last element will be common among all the elements of the array. 2.1.
