4 days ago · The Longest Common Subsequence (LCS) problem is a classic problem in computer science. Given two sequences, the task is to find the length of the longest subsequence that is common to both sequences. A subsequence is a sequence that appears in the same relative order but not necessarily consecutively. Example. Consider the two sequences: X ...
5 days ago · Explanation: “gee” is the longest common prefix in all the given strings. Input: strs [] = [“hello”, “world”] Output: -1. Explanation: There’s no common prefix in the given strings. The longest common prefix for an array of strings is the common prefix between 2 most dissimilar strings. For example, in the given array {“apple ...
3 days ago · Given two strings, find the length of the longest common substring. Input. The first line of input contains a positive integer t , which indicates the number of test cases. For each case, there are two strings in a line (length of the string = 1000). Case1: O(n 3) T = 10 , length of string = 100 Case2: O(n 2) T = 100 , length of string = 1000
3 days ago · For example, a substring of "an" will appear at least twice within the array if the target string is "banana". Further FIND and remove sub-substrings (since they would already be covered by the local LCS). For example, "an" is contained within "anan" for target text "banana". TEXTJOIN remaining common substrings into a single cell of text.
3 days ago · The Longest Increasing Subsequence (LIS) problem is to find the length of the longest subsequence of a given sequence such that all elements of the subsequence are sorted in increasing order. Here we need to print a LIS as well. In case there are multiple LIS (as shown in the example 2 below), we need to print the LIS that has lexicographic ally sm
