Which data structure is best suited for implementing 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 access elements by their index.
Step 3: Learn about linked lists. A linked list is a collection of elements called nodes, where each node points to the next one. This allows for dynamic memory allocation.
Step 4: Compare arrays and linked lists for queue implementation. Arrays allow for quick access to elements but can be inefficient for adding or removing elements from the front. Linked lists allow for efficient addition and removal of elements from both ends.
Step 5: Conclude that both arrays and linked lists can be used to implement a queue, as they both support the FIFO operations needed for a queue.
