Stack is used for parenthesis matching while working with expressions.Stack is used for expression evaluation.There are many applications of stack data structure in real life. Used to solve the problem having sequential processing Used to solve the recursive type problems There are three types of variants i.e circular queue, double-ended queue and priority queueĬan be considered as a vertical collection visualĬan be considered as a horizontal collection visual

There are no variants available for stack Two pointers are used to perform operations Only one pointer is used for performing operations The insertion end is called Rear End and the deletion end is called the Front End.Ĭomplex implementation in comparison to stack The most accessible element is called Top and the least accessible is called the Bottom of the stack Push and Pop Operation takes place from one end of the stackĮnqueue and Dequeue Operation takes place from a different end of the queue Insertion Operation is called Enqueue Operationĭeletion Operation is called Pop Operationĭeletion Operation is called Dequeue Operation Insertion Operation is called Push Operation The queue is based on FIFO(First In First Out) principle. The stack is based on LIFO(Last In First Out) principle
#STACK VS QUEUE FULL#
Let us understand the condition to check if the queue is empty or full Condition to Check if Queue is Empty Also, just like stack data structure, we can only store elements of the same data type in the queue data structure. While performing operations in the queue, there are two pointers, front pointer and rear pointer, where the front pointer is used to point the element that is added first in the queue and the rear pointer is used to point the element which is added last in the queue.

The insertion technique in the queue data structure is called enqueue operation and the deletion technique in the queue data structure is called dequeue operation. Therefore, the queue data structure follows the FIFO(First In First Out) principle, which means the element inserted first from the rear end will be the first element to be deleted from the front end. The end of the list from where the elements are inserted is called the rear end and the end from where the elements are deleted is called the front end. The queue is a linear data structure in which we can insert the element from one side of the list and delete the element from the other side of the list. Let us understand the condition to check whether the stack is empty for full: Condition to Check if Stack is Empty The most important thing to remember in the stack data structure is that it stores the elements of the same data type only. Therefore, a stack follows the LIFO (Last In First Out) principle, which means the element that is inserted last will be the first element to come out of the stack. The end of the stack used to perform all the operations is called the top of the stack. In the stack, we insert the element from one end with push operation and delete the element from the same end using pop operation.

For example, if we want to access the element in the array we can do it any time but in the case of stack data structure, there is only one sequence to access the element. Stack is a linear data structure that follows the specific order to perform the operations. At last, we will understand the practical application of stack and queue individually. In this article, we will study stack vs queue in detail along with the comparison chart between stack and queue data structure.
