#include<bits/stdc++.h>
using namespace std;
int f(int n)
{
int s,sum = 0;
for(int i = 1; i <= n; i++)
{
s = 1;
for(int j = 1; j <= i; j++)
{
s *= j;
}
sum += s;
}
return sum;
}
int main()
{
int n;
cin>>n;
cout<<f(n)<<endl;
}
就这玩意
把之前的程序翻出来在洛谷上交了一下
然后就50分了
感觉很炸裂(?)
有没有大佬来解释一下,本蒟蒻的脑子不太好用
我那么写其实是懒得打高精啦
