  1. Jun 26, 2024 · Given two strings, S1 and S2, the task is to find the length of the Longest Common Subsequence, i.e. longest subsequence present in both of the strings. A longest common subsequence (LCS) is defined as the longest subsequence which is common in all given input sequences.

  2. Jun 17, 2024 · Given an integer n and m friends and a 2D integer array paths [] [] where paths [i] is an integer array representing the path of the ith friend, return the length of the longest common subpath that is shared by every friend’s path, or 0 if there is no common subpath at all.

  3. Jun 9, 2024 · Longest Increasing Subsequence You are given an array containing $N$ integers. Your task is to determine the LCS in the array, i.e., LCS where every element is larger than the previous one.

  4. Jun 26, 2024 · Edit Distance. Last Updated : 26 Jun, 2024. Given two strings str1 and str2 of length M and N respectively and below operations that can be performed on str1. Find the minimum number of edits (operations) to convert ‘str1‘ into ‘str2‘. Operation 1 (INSERT): Insert any character before or after any index of str1.

  5. Jun 22, 2024 · A string Q is said to be a common CT-subsequence of two strings S and T if Q is a CT subsequence of both S and T. A string Q is said to be a longest common CT-subsequence (CT-LCS) of S and T if there are no common CT-subsequences of S and T longer than Q. We show an example of CT-LCS in Fig. 1.

  6. Jun 13, 2024 · Write a function that returns the longest common substring of two strings. Use it within a program that demonstrates sample output from the function, which will consist of the longest common substring between "thisisatest" and "testing123testing". Note that substrings are consecutive characters within a string.

  8. Jun 14, 2024 · The Longest Common Subsequence (LCS) problem is a dynamic programming problem in computer science. It aims to find the longest subsequence present in both input sequences, where a subsequence is a sequence that appears in the same relative order but not necessarily consecutively.
