Solving goroutines deadlock

Question

I\'ve been trying to solve this simple problem I encountered in Golang concurrency. I\'ve been searching all possible solutions, but found nothing specific to my problem(or

Answer 1

Simpler answer- one of the producers needs to close the channel, and the consumer can just range over the channel.

package main

import (
    "fmt"
    "time"
)

func producer(ch chan int, d time.Duration, num int, closer bool) {

    for i:=0; i

Of course, unless you have a situation where you know which producer will always finish last, you would not want to do this in real code. Better designs are in the WaitGroup-based patterns in the other answers. But this is the simplest way for this code to avoid deadlock.
