    min = ob.minVal(18, 23, 3, 14, 25); 
    Console.WriteLine("Minimum is " + min); 
 
    // can call with an int array, too 
    int[] args = { 45, 67, 34, 9, 112, 8 }; 
    min = ob.minVal(args); 
    Console.WriteLine("Minimum is " + min); 
  } 
}

Minimum is 10
Minimum is -1
Minimum is 3
Minimum is 8
