算法精解:最长公共子序列

最长公共子序列，英文缩写为LCS（Longest Common Subsequence）。其定义是，一个序列 S ，如果分别是两个或多个已知序列的子序列，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。而最长公共子串(要求连续)和最长公共子序列是不同的设序列 X 存储在...

[算法系列之十九]最长公共子序列

题目最长公共子序列分析有两个字符串S1和S2，求一个最长公共子串，即求字符串S3，它们同时是S1和S2的子串，且要求它们的长度最长，并确定这个长度。这个问题我们称之为最长公共子序列问题。与求最长递增子序列一样，我们首先将原问题分割成一些子问题，我们用dp[i][j]表示S1中前i个字符和S2...
