Stack using Linked List
Detailed guide and Python implementation for the 'Stack using Linked List' problem.
Problem Statement
Write a function execute_stack_linked_list(operations) that simulates a Stack using a singly linked list. The input is a list of tuples operations where each tuple is either ("push", val) or ("pop",). Return a list of popped values. If popping from an empty stack, return None.
- •0 <= len(operations) <= 1000
Examples
operations = [("push", 10), ("push", 20), ("pop",)][20]
Push 10, push 20. Pop returns the top element 20.
