// Multiply multiplies two integers and returns the result.
//
// Args:
//        a: The first integer
//        b: The second integer
//
// Returns:
//        The product of a and b
func Multiply(a, b int) int {

// Bad:
func Rename(oldname, newname string) string

// Good:
func UpdateName(oldname, newname string) string

// Averages calculates the average of a list of integers.
//
// Args:
//        numbers: The list of integers to average
//
// Returns:
//        The average of the numbers
func Average(numbers ...int) float64 {
    sum := 0.0
    for _, number := range numbers {

    }
    return sum / float64(len(numbers))
}

// Example demonstrates how to use the Average function.
func ExampleAverage() {
    average := Average(1, 2, 3, 4, 5)
    fmt.Println(average) // Output: 3
}

// See also:
//
// - Max: Returns the larger of two numbers
// - Min: Returns the smaller of two numbers
