#include<bits/stdc++.h>
using namespace std;
constexpr int N=2e5+5;
int main(){
std::ios::sync_with_stdio(0);cin.tie(0);cout.tie(0);
int t;cin>>t;
while(t--){
double x;cin>>x;x=1/x;
double ans=0,w=1;
for(int k=0;k<=x;k++){
if(k){w=w/k*-1;}
ans+=w*pow(x-k,k)*pow(M_E,x-k);
}
cout<<fixed<<setprecision(10)<<ans<<'\n';
}
}
这程序好像有点Bug，我给组数据试试？
