LCS Time Limit: 1 Sec Memory Limit: 256 MB 题目连接 http://acm.hdu.edu.cn/showproblem.php?pid=5495 Description 你有两个序列\{a_1,a_2,...,a_n\}{a​1​​,a​2​​,...,a​n​​}和\{b_1,b_2,...,b_n\}{b​1​​,b​2​​,...,b​n​​}. 他们都是11到nn的一个排列. 你需要找到另一个排列\{p_1,p_2,...,p_n\}{p​1​…

Problem Description You are given two sequence {a1,a2,...,an} and {b1,b2,...,bn}. Both sequences are permutation of {,,...,n}. You are going to find another permutation {p1,p2,...,pn} such that the length of LCS (longest common subsequence) of {ap1,a…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1423 好坑啊..还有公共串为0时的特殊判断,还有格式错误..看Discuss看知道除了最后一组测试数据之外都需要空行.. 其余的会LCS打印路径就行了. 法一: ///公共最长上升子序列 #include <iostream> #include <stdio.h> #include <string.h> #include <stdlib.h> #include…

hdu 1503 不知道最后怎么输出,因为公共部分只输出一次.有人说回溯输出,感觉好巧妙!其实就是下图,输出的就是那条灰色的路径,但是初始时边界一定要初始化一下,因为最第一列只能向上走,第一行只能向左走.我用1表示向上走,2向左上方走,3向左走. 刚开始输入字符串时有两种方法,直接输入:或从地址后一位输入,即此时数组起始编号为1.直接输入时,dp[i][j]表示的是以s1[i-1],s2[j-1]为结尾LCS,另一种则就是表示以s1[i],s2[j]为结尾的LCS.两者在路径输出时有些差别,以前…

a typical variant of LCS algo. the key point here is, the dp[][] array contains enough message to determine the LCS, not only the length, but all of LCS candidate, we can backtrack to find all of LCS. for backtrack, one criteria is dp[i-1][j]==dp[i][…
