Sum the elements of a list
<code go> 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)
} </go>
