swap

Instructions

• Write a function that swaps the contents of two pointers to an int (*int).

Expected function

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

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

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

And its output :

$ go run .
1
0
$
