After reading instructions, complete required steps:

Implement the Queue class in Python. Make sure it follows the structure of the pseudocode provided below.

Test your implementation by instantiating an object of the Queue class, and then using the enqueue method to add some items to the queue.

Test the dequeue method by removing items from the queue and printing them out. Make sure the items are removed in the correct order $($the first item added to the queue should be the first item to be removed$).$

Test the size method by checking the size of the queue after adding and removing items. Make sure it returns the correct size of the queue.

When you're finished, submit your implementation along with the test output to show that it works correctly.

Class Queue

attribute: queue

function $\_\_$init$\_\_()$

set queue to empty list

function enqueue$($item$)$

add item to the end of queue

function dequeue$()$

if the size of queue is less than $1$

return None

remove the first item from queue and return it

function size$()$

return the size of queue

Example usage inside main

Create an object

Test the functions above.
