Write a C++ program to check three given integers and return true if one of them is 20 or more less than one of the others

#include <iostream>
using namespace std;

bool test(int x, int y, int z)
        {
          return abs(x - y) >= 20 || abs(x - z) >= 20 ||
                   abs(y - z) >= 20;
        }
        
        
int main() 
 {
  cout << test(11, 21, 31) << endl;  
  cout << test(11, 22, 31) << endl;  
  cout << test(10, 20, 15) << endl;  
  return 0;    
}
