You should provide a 'Dynamic Programming' algorithm to solve this problem. Dr. Watson has been kidnaped! Sherlock Holmes was contacted by the kidnapper for ransom. Moments later he received a message from Dr. Watson's phone. The message contained three random strings. Sherlock being Sherlock, was able to deduce immediately that Dr. Watson was trying to give a hint about his location. He figured out that the longest common subsequence between the 3 words is the location. But since it was too easy for him, he got bored and asked you to find out what the actual location is. Your task is to find the longest common subsequence from the 3 given strings before it is too late. Definitions: Subsequence - A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements. For instance, given a sequence "drew"; "d", "w", "de", "drw", "drew" are all examples of valid subsequences (there are also others), while "er", "wdre" are not. Note: W is a common subsequence of X, Y, and Z if and only if W is a subsequence of X, W is a subsequence of Y and W is a subsequence of Z. If a common subsequence does not exist, return "Does not exist" (without quotes) Your goal is to find the longest common subsequence, not just any common subsequence. Input Format Three lines, each containing a string. Note: Each string only contains lowercase English alphabet letters (i.e. a, b, ..., y, z). Constraints 1 1 import java.io.*; 2 import java.util.*; 3 4 public class Solution { Java 8 * XX 5 6- public static void main(String[] args) { 7 /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */ 8 } 9}
