How to create and use a queue (FIFO) in Go using the container/package package?

To create and use a queue (FIFO) in Go using the container/package, follow these steps:

Step 1: Import necessary packages:

import (
	"container/list"
	"fmt"
)

Step 2: Create a new queue:

q := list.New()

Step 3: Insert elements into the queue:

q.PushBack("element1")
q.PushBack("element2")
q.PushBack("element3")

Step 4: Retrieve and remove the first element from the queue (FIFO):

firstElement := q.Front()
q.Remove(firstElement)
fmt.Println(firstElement.Value)

Step 5: Check if the queue is empty:

isEmpty := q.Len() == 0
fmt.Println(isEmpty)

Step 6: Iterate over the elements in the queue:

for e := q.Front(); e != nil; e = e.Next() {
	fmt.Println(e.Value)
}

Here's a complete example:

import (
	"container/list"
	"fmt"
)

func main() {
	q := list.New()

	q.PushBack("element1")
	q.PushBack("element2")
	q.PushBack("element3")

	firstElement := q.Front()
	q.Remove(firstElement)
	fmt.Println(firstElement.Value)

	isEmpty := q.Len() == 0
	fmt.Println(isEmpty)

	for e := q.Front(); e != nil; e = e.Next() {
		fmt.Println(e.Value)
	}
}

This example demonstrates how to create a queue using the container/list package and perform basic operations like adding elements, retrieving and removing elements, checking if the queue is empty, and iterating over the elements in the queue.
