import "fmt"

func main() {
	arr := []int{10, 20, 30, 40, 50}
	chnl := make(chan int)

	go FunSumNumbers(arr[:len(arr)/2], chnl)
	go FunSumNumbers(arr[len(arr)/2:], chnl)

	num1 := <-chnl
	num2 := <-chnl

	fmt.Println("Sum of two numbers in first goroutine: ", num1)
	fmt.Println("Sum of two numbers in second goroutine: ", num2)

	fmt.Println("Total : ", num1+num2)
}

func FunSumNumbers(numbers []int, chnl chan int) {
	result := 0
	for _, value := range numbers {
		result += value
	}
	chnl <- result
}
