贪心 每一次取最小的两个数,注意相加的数也要算' #include<cstring> #include<iostream> #include<cstdio> #include<algorithm> #include<string> #include<queue> using namespace std; int main() { long long a[5005],i; long long b[5005],n; priority_…
Yup!! The problem name reects your task; just add a set of numbers. But you may feel yourselvescondescended, to write a C/C++ program just to add a set of numbers. Such a problem will simplyquestion your erudition. So, lets add some avor of ingenuity…

题意:给你n个数的集合,每次选两个删除,把它们的和放回集合,直到集合的数只剩下一个,每次操作的开销是那两个数的和,求最小开销. Huffman编码.Huffman编码对于着一颗二叉树,这里的数对应着单词出现的频度,每次合并深度最大的结点,选频度最小的两个. 用两个队列类似归并排序,合并一下. #include<bits/stdc++.h> using namespace std; ; int q1[maxn]; int q2[maxn]; #define GetMin(x)\ if(head1…
