1. Using an array An array is a collection of ordered and indexed elements. We can use an array to store the elements of the queue and use the array functionspush()andshift()to add and remove elements from the end and the beginning of the array, respectively, which correspond to the ...
Note ? The implementation of a queue using an array is not the most efficient method due to frequent enqueue and dequeue operations. Example 1In the following Swift program, we will implement a queue data structure using structure. Here we define a queue structure with enqueue, dequeue, top,...
* Initialize your data structure here. */function__construct(){$this->stack1 = [];$this->stack2 = []; }/** * Push element x to the back of queue. *@paramInteger $x *@returnNULL */functionpush($x){while(!$this->empty()) {$this->stack2[] =array_pop($this->stack1); }$...

And, we can easily keep track of the last element using a pointer called top. What is a Queue? A Queue is a linear data structure in which a user can insert and delete an element on the different end. The process of insertion in the queue is known as enqueue and the element will ...
Here, we will implement a Linear Queue using Array. Linear Queue follows FIFO (First In First Out) property, which means first inserted elements, deleted first. In linear queue there are two pointers are used:FRONT: It points to the location from where we can delete an item from the ...
