![]() ![]() It takes O(1) time, as the top always points to the newly inserted node. pop(): It removes an element from the top of the stack.It takes O(1) time, as each node is inserted at the head/top of the linked list. push(): It inserts an element to the top of the stack.Operations performed on Stackįollowing operations can be performed on a stack: Dynamic allocation for each new node mitigates overflow concerns in this linked list implementation. Unlike arrays, linked lists offer flexibility as the stack can dynamically grow or shrink, eliminating the risk of overflow imposed by array capacity restrictions. The stack's top pointer, acting as the head of the stack, facilitates pushing and popping at the list's head. A top variable guides operations like Pop, Push, Peek, and Display. Implementing a stack using singly linked lists involves aligning standard linked list operations with stack operations, adhering to the Last In, First Out (LIFO) principle. In this approach, the topmost node's address field contains null. ![]() Stack overflow occurs when insufficient memory heap space is available for node creation. In linked list implementation, nodes are non-contiguously maintained in memory, each with a pointer to its successor node in the stack. Despite using different data structures, time complexities for stack operations (push, pop, peek) remain consistent. Linked lists provide an alternative to arrays for implementing a stack, dynamically allocating memory. ![]()
