tp()函数中的ans一开始初始化大了,然后玄学RE-->TLE-->WA
STL暴力
#include<bits/stdc++.h> using namespace std; priority_queue<int>q; int n,m,qt,u,v,t,a,cnt; double p; int main() { scanf("%d%d%d%d%d%d",&n,&m,&qt,&u,&v,&t);p=(double)u/v; for(int i=1;i<=n;i++){scanf("%d",&a);q.push(a);} for(int i=1;i<=m;i++) { int top=q.top()+(i-1)*qt; q.pop(); int a1=floor(p*(double)top),a2=top-a1; if(i%t==0)cout<<top<<" "; q.push(a1-i*qt);q.push(a2-i*qt); }cout<<endl; while(!q.empty()) { ++cnt; if(cnt%t==0)cout<<q.top()+m*qt<<" "; q.pop(); } }
