Circular Queue
Detailed guide and Python implementation for the 'Circular Queue' problem.
Problem Statement
Write a function execute_circular_queue(size, operations) that simulates a Circular Queue of maximum size size. The input is an integer size and a list of tuples operations of the form ("enqueue", val) or ("dequeue",). If enqueue succeeds, return True, otherwise False. If dequeue succeeds, return the dequeued value, otherwise None.
- •1 <= size <= 100
- •0 <= len(operations) <= 1000
Examples
size = 3, operations = [("enqueue", 1), ("enqueue", 2), ("enqueue", 3), ("enqueue", 4), ("dequeue",)][True, True, True, False, 1]
Enqueue 1, 2, 3 succeed. Enqueue 4 fails because queue is full. Dequeue returns 1.
