PYTHON大法
```c
#include<iostream>
#include<math.h>
using namespace std;
long long a[99999999],b[99999999];
double kill,l=99999999999;
int main(){
int i,j,n;
cin>>n;
for(i=1;i<=n;i++){
cin>>a[i]>>b[i];
}
for(i=1;i<n;i++)
for(j=i+1;j<=n;j++){
kill=sqrt((a[j]-a[i])*(a[j]-a[i])+(b[j]-b[i])*(b[j]-b[i]));
if(l>kill)l=kill;
}
printf("%.4lf",l);
}
