题目描述 This problem differs from one which was on the online contest. The sequence a1,a2,...,an a_{1},a_{2},...,a_{n} a1,a2,...,an is called increasing, if ai<ai+1 a_{i}<a_{i+1} ai<ai+1 for i<n i<n i<n . The sequence s1,s2,...,sk s_{1…
Virus We have a log file, which is a sequence of recorded events. Naturally, the timestamps are strictly increasing. However, it is infected by a virus, so random records are inserted (but the order of original events is preserved). The backup log…

This is a problem from ZOJ 2432.To make it easyer,you just need output the length of the subsequence. InputEach sequence is described with M - its length (1 <= M <= 500) and M integer numbers Ai (-2^31 <= Ai < 2^31) - the sequence itself.Outpu…

题目大意:给定两个大小为n的数组,让你找出最长公共上升子序列的长度. 分析:这是一个比较好的dp题,LIS和LCS两大经典线性dp问题相结合,简称LCIS. 代码(O(n*n*n)写法): #include<bits/stdc++.h> using namespace std; ; int a[maxn],b[maxn]; int dp[maxn][maxn]; int main() { int n; cin >> n; ; i <= n; i++) cin >>…
