HDU 1159 题目大意:给定两个字符串,求他们的最长公共子序列的长度 解题思路:设字符串 a = "a0,a1,a2,a3...am-1"(长度为m), b = "b0, b1, b2, b3 ... bn-1"(长度为n), 它们的最长公共子序列为c = "c0, c1, c2, ... ck-1",长度为k, dp[i][j]定义为子串 "a0,a1,...,ai-1" 和 子串"b0,b1,...,bj-1…

HDU 1159 Common Subsequence 最长公共子序列 题意 给你两个字符串,求出这两个字符串的最长公共子序列,这里的子序列不一定是连续的,只要满足前后关系就可以. 解题思路 这个当然要使用动态规划了. 这里\(dp[i][j]\)代表第一个串的前\(i\)个字符和第二个串的前\(j\)个字符中最长的公共子序列的最长长度,递推关系如下: \[ d[i][j]= \begin{cases} dp[i-1][j-1]+1 & \text{if} &str1[i]==str2[j…
