Advance Practical PHP Explain DS Stack, LinkedList, Tree, Queue - video 115h

Queue (FIFO - First-In, First-Out) A Queue is a linear data structure that follows the FIFO (First-In, First-Out) principle. Think of it like people waiting in line: the first person to get in line is the first person to be served and leave the line. Key Operations: Enqueue: Adds an element to the rear (back) of the queue. Dequeue: Removes and returns the element from the front of the queue. Front: Returns the element at the front without removing it. Standard PHP Implementation: Using the SplQueue Class The SplQueue::enqueue() function is an inbuilt function in PHP which is used to add the element to the queue. The most efficient and standard way in modern PHP is to use the dedicated SplQueue class, which is optimized for queue operations. Note: SplQueue often stores elements in reverse for internal efficiency, but it operates FIFO. The SplQueue::dequeue() function is an inbuilt function in PHP which is used to dequeues the node from the queue. Dequeue: Remove and return the element from the front Parameters: This function accepts a single parameter $val which specifies the value for add (enqueue) element. Return Value: This function does not return any value.

Parameters: This function does not accept any parameter. Return Value: This function return the value of the dequeued node. Below programs illustrate the SplQueue::dequeue() function in PHP: Big O Notation for Queue Operation Big O Notation Description Enqueue O(1) Adding an element to the rear is constant time. Dequeue O(1) Removing the element from the front is constant time. Front O(1) Viewing the front element is constant time. —————————————————- Here are the html/scripts in an txt and php extension. ——————————————————- ——————————————————- https://convertowordpress.com/dataStr... ——————————————————- ——————————————————- Check out the PHP manual that is available online: https://www.php.net/docs.php If you want a developer to create your web design project.
