The Longest Common Substring (LCS) problem is as follows: Given two strings s and t, find the length of the longest string r, which is a substring of both s and t. This problem is a classic application of Dynamic Programming. Let's define the sub-pro…

LCS2 - Longest Common Substring II A string is finite sequence of characters over a non-empty finite set Σ. In this problem, Σ is the set of lowercase letters. Substring, also called factor, is a consecutive sequence of characters occurrences at leas…

原题链接在这里:http://www.lintcode.com/en/problem/longest-common-substring/# 题目: Given two strings, find the longest common substring. Return the length of it. The characters in substring should occur continuously in original string. This is different with …

Given two strings, find the longest common substring. Return the length of it. Example Given A = "ABCD", B = "CBCE", return 2. public class Solution { /** * @param A, B: Two string. * @return: the length of the longest common substring…

http://www.spoj.com/problems/LCS2/ 发现了我原来对sam的理解的一个坑233 本题容易看出就是将所有匹配长度记录在状态上然后取min后再对所有状态取max. 但是不要忘记了一点:更新parent树的祖先. 为什么呢?首先如果子树被匹配过了,那么长度一定大于任意祖先匹配的长度(甚至有些祖先匹配长度为0!为什么呢,因为我们在匹配的过程中,只是找到一个子串,可能还遗漏了祖先没有匹配到,这样导致了祖先的记录值为0,那么在对对应状态取min的时候会取到0,这样就wa了.而…
