Instructions

  • Write a function that takes two pointers to an int (*int) and swaps their contents.

Expected function

func Swap(a *int, b *int) {

}

Usage

Here is a possible program to test your function :

package main

import "fmt"

func main() {
	a := 0
	b := 1
	Swap(&a, &b)
	fmt.Println(a)
	fmt.Println(b)
}
