Try executing the code below to see the result.

package main

import (
	"fmt"
)

func main() {
	ch := make(chan int, 2)
	ch <- 1
	ch <- 2
	<-ch
	close(ch)
	a := <-ch
	b := <-ch
	fmt.Println(a, b)
}




# Explanation ##
The `ch` channel is a buffered channel with a capacity of `2` (we can check this with `cap(ch)`). Send two values to `ch`, `1` and `2`, because sending another one will result in a **deadlock**.
