Average

Returns the average of two or more numbers.

• Use range to iterate over the values of nums, adding each value to sum.
• Return the result of dividing sum with len(nums).

func Average(nums ...float64) float64 {
    sum := float64(0)
    for _, num := range nums {
        sum += num
    }
    return sum / float64(len(nums))
}

Average(1.0, 4.0) // 2.5
Average([]float64{1.0, 2.0, 3.0}...) // 2.0
