Longest Ordered Subsequence DescriptionA numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK…

POJ2533裸的LIS,时间复杂度为O(n^2) #include<iostream> #include<cstdio> using namespace std; +; int a[MAXN]; int dp[MAXN]; int n,ans; int main() { scanf("%d",&n); ;i<n;i++) { scanf("%d",&a[i]); dp[i]=; } ans=-; ;i<n;i++…

题目链接: http://poj.org/problem?id=2533 题意:第一个数n,接下来n个数,>  ....求最长上升子序列. 这道题有两种解法,第一种是通解,也适用于别的LIS. 代码1: #include<cstdio> #include<algorithm> using namespace std; ],dp[]; int main() { int n; ) { ; i<=n; i++) { scanf("%d",&a[i]…

本题大意:和LIS一样 本题思路:用dp[ i ]保存前 i 个数中的最长递增序列的长度,则可以得出状态转移方程dp[ i ] = max(dp[ j ] + 1)(j < i) 参考代码: #include <iostream> #include <cstring> #include <algorithm> using namespace std; ; int a[maxn], dp[maxn]; int main () { ; cin >> n;…
