Queue using Linked List
Detailed guide and Python implementation for the 'Queue using Linked List' problem.
Problem Statement
Write a function execute_queue_linked_list(operations) that simulates a Queue using a singly linked list. The input is a list of tuples operations where each tuple is either ("enqueue", val) or ("dequeue",). Return a list of dequeued values. If dequeued from empty queue, return None.
- •0 <= len(operations) <= 1000
Examples
operations = [("enqueue", 5), ("enqueue", 10), ("dequeue",)][5]
Enqueue 5, enqueue 10. Dequeue returns 5.
