#include <iostream>


using namespace std;

int main(){
    int n;
    int b[3][2];
    int out=1e7;
    cin>>n;
    for(int i=0;i<3;i++){
        cin>>b[i][0]>>b[i][1];
    }
    for(int i=0;i<3;i++){
        int count;
        if(n%b[i][0] == 0){
            count = n/b[i][0];
        }else{
            count = n/b[i][0] + 1;
        }
        int mi = count*b[i][1];
        out = out<mi?out:mi;
    }
    cout<<out<<endl;



    return 0;
}

为什么我这个代码样例三都没有通过,但是却能ac啊????????
