Go Golang - pointers exercise, swap x and y

Go Golang - pointers exercise, swap x and y

package main
 
import "fmt"
 
func swap(px, py *int) {
	tempx := *px
	tempy := *py
	*px = tempy
	*py = tempx
}
func main() {
    x := int(1)
	y := int(2)
	fmt.Println("x was", x)
	fmt.Println("y was", y)
    swap(&x, &y)
	
	fmt.Println("x is now", x)
	fmt.Println("y is now", y)
}

Approach 1: Using a temporary(temp) variable to store the value of x

package main
import "fmt"

func swap(x *int, y *int) {
	temp := *x
	*x = *y
	*y = temp
}

func main(){
	x,y := 5,10
	fmt.Println("Before SWAP: ",x,y)
	swap(&x,&y)
	fmt.Println("After SWAP:  ",x, y)
}

/*
Output:
Before SWAP:  5 10
After SWAP:   10 5
*/

Approach 2: No mediators used

package main
import "fmt"

func swap(x *int, y *int) {
	*x,*y = *y,*x
}

func main(){
	x,y := 5,10
	fmt.Println("Before SWAP: ",x,y)
	swap(&x,&y)
	fmt.Println("After SWAP:  ",x, y)
}

/*
Output:
Before SWAP:  5 10
After SWAP:   10 5
*/

Ty, bro for your useful code.
