#Circular queue vs circular linked list stack overflow how to

The main advantage of using a linked list over arrays is that it is possible to implement a stack that can shrink or grow as much as needed. The first node has a null in the link field and second node-link has the first node address in the link field and so on and the last node address is in the “top” pointer. which is the “head” of the stack where pushing and popping items happens at the head of the list. In the stack Implementation, a stack contains a top pointer.

Let us learn how to perform Pop, Push, Peek, and Display operations in the following article: So we need to follow a simple rule in the implementation of a stack which is last in first out and all the operations can be performed with the help of a top variable. To implement a stack using the singly linked list concept, all the singly linked list operations are performed based on Stack operations LIFO(last in first out) and with the help of that knowledge, we are going to implement a stack using a singly linked list. Stack | Set 4 (Evaluation of Postfix Expression).Maximum product of indexes of next greater on left and right.

Next greater element in same order as input.

Next Greater Element (NGE) for every element in given Array.
