```
#include<bits/stdc++.h>
using namespace std;
int a,b[10001],sum;
void s(int i)
{
for(int j = 1 ; j<=a ; j++){
for(int z = 1 ; z<=a ; z++){
if(b[i]==b[j]+b[z] && i != j && i != z && j != z){
sum++;
return ;
}
}
}
}
int main(){
cin>>a;
for(int i=1;i<=a;i++){
cin>>b[i];
}
//sort(b+1,b+a+1);
for(int i = 1 ; i<=a ; i++){
s(i);
}
cout<<sum;
return 0;
}
