```cpp
#include<iostream>
using namespace std;
int main() {
int number[100], a[100];
int n, num = 0;

for(int i = 0; i < n; i++) {
cin >> number[i];
a[i] = number[i]; }
for(int i = 0; i < n; i++) {
for(int j = i + 1; j < n; j++) {
for(int z = 0; z < n; z++) {
int c = number[z];
number[z] = 0;
if(c == number[j] + number[i]) { num++; }
number[z] = c; } } }
cout << num; return 0; }
