题意:给定 n 个数,让你修改最少的数,使得这是一个不下降序列. 析:和3670一思路,就是一个LIS,也可以直接暴力,因为只有两个数,所以可以枚举在哪分界,左边是1,右边是2,更新答案. 代码如下: #include <cstdio> #include <string> #include <cstdlib> #include <cmath> #include <iostream> #include <cstring> #includ…
/* 一开始并没有想出On的正解 后来发现题解的思路也是十分的巧妙的 还是没能把握住题目的 只有1 2这两个数的条件 dp还带练练啊 ... */ #include<iostream> #include<cstdio> #include<cstring> #define maxn 100010 using namespace std; int n,a[maxn],Q[maxn],H[maxn],ans=0x7fffffff; int main() { scanf(&qu…
