Stack is a data structure used to store and retrieve data in a last-in-first-out (LIFO) manner. ROM cannot be used as stack.
Stack is a collection of elements with two main operations: push (add element) and pop (remove element).
Stack follows the LIFO principle, meaning the last element added is the first one to be removed.
Stack can be implemented using arrays or linked lists.
ROM (Read-Only Memory) cannot be used as sta...

You are provided with the head of a linked list containing integers. Your task is to determine if the linked list is circular.
Detect if a given linked list is circular by checking if it forms a closed loop.
Traverse the linked list using two pointers, one moving at double the speed of the other.
If the two pointers meet at any point, the linked list is circular.
If the faster pointer reaches the end of the list (NULL), the linked list is not circular.
