Questions & Step-by-Step Solutions
Which of the following data structures can be used to implement a queue?
Step 1: Understand what a queue is. A queue is a data structure that follows the First In, First Out (FIFO) principle, meaning the first element added is the first one to be removed.
Step 2: Learn about arrays. An array is a collection of elements stored in a contiguous block of memory. You can add and remove elements from the front and back of the array to simulate queue operations.
Step 3: Learn about linked lists. A linked list is a collection of nodes, where each node contains data and a reference to the next node. You can easily add and remove nodes from the front and back, making it suitable for queue operations.
Step 4: Compare arrays and linked lists. Both can be used to implement a queue because they can handle adding elements to the back and removing elements from the front, which is essential for FIFO behavior.
Step 5: Conclude that both arrays and linked lists are valid data structures for implementing a queue.
