Stacks and Queues are important when it comes to Data Structures. In this tutorial, we will be covering the entire (A-Z) of Stacks and Queues. Master Data Structures and Algorithm now: https://bit.ly/3KnRrut 🔹 What are Stacks and Queues in Data Structure and Algorithm? - Stack is a last in first out (lifo) linear data structure. Imagine stack in DS Algo as a pile of blocks. You can remove the block at the top quite easily. But if you have to remove the block at the end of the pile, you have to remove all the other blocks as well. Elements in Stack can be inserted or deleted only from one side. The insertion of an element into a stack is called push operation and the deletion of an element from the stack is called the pop operation. - Queue is a first in first out (fifo) linear data structure. Elements in Queue can only be inserted and deleted from opposite sides. The insertion of an element in Queue is called as en queue operation and the deletion of an element is referred to as a dequeue operation.
