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…
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_…
解法和合并果子是一样的, 每次取最小的两个, 更新答案, 加入队列 #include<cstdio> #include<queue> #define REP(i, a, b) for(int i = (a); i < (b); i++) using namespace std; int main() { int n, x; while(~scanf("%d", &n) && n) { priority_queue<int, v…
A pair of numbers has a unique LCM but a single number can be the LCM of more than one possiblepairs. For example 12 is the LCM of (1, 12), (2, 12), (3,4) etc. For a given positive integer N, thenumber of different integer pairs with LCM is equal to N…
