c++解刷题统计

解题思路:

注意事项:

参考代码:

#include<iostream>

using namespace std;

int main(){

long long a,b,n;

cin>>a>>b;

cin>>n;

long count = 0;

if(n > 5 * a + 2 * b){

count = n / (5 * a + 2 * b) * 7;

n %= 5 * a + 2 * b;

}

if(n > 5 * a){

count+=5;

n -= 5 * a;

for(int i = 0;i < 2;i++){

n -= b;

count++;

if(n <= 0)

break;

}

}else{

for(int i = 0; i < 5;i++){

n -= a;

count++;

if(n <= 0)

break;

}

} 

cout<<count<<endl;

return 0;

}
