![]() push() : Insert a new element into the stack i.e just inserting a new element at the beginning of the linked list.Here each new node will be dynamically allocated. Using an array will put a restriction on the maximum capacity of the array which can lead to stack overflow. 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.
