// EXERCISE
// Average calculator has a flaw.
// It divides the numbers by the length of the array.
// This results in wrong calculatio.
//
// For example:
//
// When you run it like this:
//   go run main.go 1 5
// It tells you that the average number is:
//  1.2
// Whereas, actually, it should be 3.
//
// Fix this error.
// So that, it will output 3 instead of 1.2
//
// Do not change the length of the array.
