## Full example

    package main
    import "fmt"

    func sum(a []int, c chan int) {
    	sum := 0
    	for _, v := range a {
    		sum += v
    	}
    	c <- sum // send sum to c
    }

    func main() {
    	a := []int{7, 2, 8, -9, 4, 0}

    	c := make(chan int)
    	go sum(a[:len(a)/2], c)
    	go sum(a[len(a)/2:], c)
    	x, y := <-c, <-c // receive from c

    	fmt.Println(x, y, x+y)
    }
