Write a C++ program to compute the sum of three given integers. If the two values are same return the third value

#include <iostream>
using namespace std;

int test(int x, int y, int z)
        {
            if (x == y && y == z) return 0;
            if (x == y) return z;
            if (x == z) return y;
            if (y == z) return x;
            return x + y + z;
        }
        
int main() 
 {
  cout << test(4, 5, 7) << endl;  
  cout << test(7, 4, 12) << endl;  
  cout << test(10, 10, 12) << endl;  
  cout << test(12, 12, 18) << endl;    
  return 0;    
}
