// Use of golang slice
func main() {
    // initialise the slice with 10 zero ints
	slice := make([]int, 10)
    // fillup with random ints
	fillSliceWithRand(slice)
    // prints the slice
	print(slice)
    // passes the slice by reference and reverse the slice
	reverse(slice)
    // prints the slice again
	print(slice)
}

// reverse method reverse the slice
func reverse(a []int) {
	l := len(a)
	for i := 0; i < l/2; i ++ {
		x := a[l-i-1]
		a[l-i-1] = a[i]
		a[i] = x
	}
}
// print method prints all ints of the slice
func print(a []int) {
	for _, v := range a {
		fmt.Printf("%d ", v)
	}
	fmt.Println()
}
// fillSliceWithRand method fills the slice with random ints
func fillSliceWithRand(a []int) {
	for i := 0; i < len(a); i++ {
		a[i] = rand.Intn(100)
	}
}
/**
## Slice in golang
	- Slices hold references to an underlying array, and if you 
      assign one slice to another, both refer to the same array.
	- If a function takes a slice argument, changes it makes to 
      the elements of the slice will be visible to the caller, 
      analogous to passing a pointer to the underlying array.
