Golang for Programmers

Mastering concurrency in Go can make you a highly sought-after developer in today's job market, where multi-core devices are becoming common. The good news is that concurrency in Go is straightforward and efficient, thanks to Go’s robust support for concurrency out of the box. In fact, it's easier and faster to implement than in other major programming languages.
In this module, we'll begin with a general introduction to concurrency and build up to more advanced concepts like Go parallelism. We'll also dive into common patterns, including Go Fan-In Fan-out, which will make our code more efficient. By the end of this module, you'll be equipped to write high-performance, concurrent applications using Go.

What is the output of the following program?

```Go
func main(){
    var count int
    go func(){
        count++
        fmt.Println(count)
    }()
   go func(){
        count=2
        fmt.Println(count)
 }()
}

  
```

What is the output of the following program?
<pre><code class="language-Go">func main(){
 var count int
 go func(){
 count++
 fmt.Println(count)
 }()
 go func(){
 count=2
 fmt.Println(count)
 }()
}

What is the output of the following program?

```
func main() { 
 channel1 := make(chan string)
 select {
 case <-channel1:
 default:
