接下来我们来了解一下什么是最长公共子序列(Longest Common Subsequence),我们常说的LCS就是这个最长公共子序列: 先看看维基百科是怎么定义的: 一个数列S,如果分别是两个或多个已知数列的子序列,且是所有符合此条件序列中最长的,则S 称为已知序列的最长公共子序列。 好像跟前面的最长公共子串差不多哦? 这两个还...
Substring, also called factor, is a consecutive sequence of characters occurrences at least once in a string. Now your task is simple, for two given strings, find the length of the longest common substring of them. Here common substring means a substring of two or more strings. 输入格式 The...

In this problem, Σ is the set of lowercase letters. Substring, also called factor, is a consecutive sequence of characters occurrences at least once in a string. Now your task is simple, for two given strings, find the length of the longest common substring of them. Here common substring ...
One is to compute the length of the longest common substring of two given SLP-compressed strings, and the other is to compute all palindromes of a given SLP-compressed string. In order to solve these problems efficiently (in polynomial time w.r.t. the compressed size) decompression is never...

For the two input sequences, X and Y , of lengths n andmand a constraint string, P, of length r, the goal is to find the longest common subsequence, Z, of X and Y that excludes P as a substring. The problem and its solution were first proposed by Chen and Chao, but we found ...
Question: Longest Common Substring Problem: Given two string sequences write an algorithm to find, find the length of longest substring present in both of the string sequences. A longest common substring is a sequence of characters that appears in the...
