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.

In concurrent programming, it is the job of a programmer to design and structure the subtasks of any task so they can be executed independently.

Some processes in your program are unable to perform their work because they are not being allocated a processor. This an example of:

Which of the following best describes the given code?
```
func main() {
    n := 10;
    
    go func(){
      n++
    }()

    go func(){
    	n--
    	fmt.Println(n) 
    }()
    
    fmt.Println(n) 

}
