我们发现,将a数组排序后记为c数组,那么如果我们每次更改最后一个值等于a[x]的,c依然有序! b数组同理搞一个d数组,这样我们就可以直接算了。 因为b数组的对应位置也是可以匹配到的最大的,它也是有序的,满足我们的思路。 点击查看代码 void solve() { int n, q; std::cin >> n >> q; std::vector a...
A Tender Carpenter 给一个数列分是否存在至少2种划分方式使得划分后每个子段中的数任取(可重复取)3个都能作为三角形的3条边长。 #include<bits/stdc++.h> using namespace std; #define For(i,n) for(int i=1;i<=n;i++) #define Fork(i,k,n) for(int i=k;i<=n;i++) #define ForkD(i,...
However, the rapid expansion of system scale, refined management and operational constraints has greatly increased the optimization difficult of POHS. As a result, it is of great importance to develop effective methods that can ensure the computational efficiency of POHS. The progressive optimality ...
