Both Queue and Stack are linear data structures and are used to store data. Stack uses the LIFO principle to insert and delete its elements. A Queue uses the FIFO principle. In this tutorial, we will learn how to reverse a stack using Queue. Reversing means the last element of the Stack...

List reversal is useful when working with specific data structures that require reverse-order processing. For instance, reversing the list in a stack (LIFO - Last In, First Out) enables easy access to elements in their insertion order. Similarly, list reversal is beneficial in queue-based applic...
