题目大意:
有一个农夫要把一个木板钜成几块给定长度的小木板,每次锯都要收取一定费用,这个费用就是当前锯的这个木版的长度
给定各个要求的小木板的长度,及小木板的个数n,求最小费用
思路:
优先队列
1 #include<iostream> 2 #include<algorithm> 3 #include<cstdio> 4 #include<cstring> 5 #include<queue> 6 #include<vector> 7 using namespace std; 8 typedef long long ll; 9 int n; 10 int main() 11 { 12 while(scanf("%d", &n) != EOF) 13 { 14 priority_queue<int, vector<int>, greater<int> >q; 15 int x; 16 for(int i = 0; i < n; i++) 17 { 18 scanf("%d", &x); 19 q.push(x); 20 } 21 ll ans = 0; 22 while(q.size() > 1) 23 { 24 int a = q.top(); 25 q.pop(); 26 int b = q.top(); 27 q.pop(); 28 q.push(a + b); 29 ans += (a + b); 30 } 31 cout<<ans<<endl; 32 } 33 return 0; 34 }
