Implement swap() which swaps the value of two variables without using a third variable.
Solution
package main
import "fmt"
func main() {
fmt.Println(swap())
}
func swap() []int {
a, b := 15, 10
Run
While this may be tricky in other languages, Go makes it easy.
We can simply include the statement b, a = a, b, what data the variable references without engaging with either value.
