Which data structure would you use 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 use an array to implement a queue by keeping track of the front and rear positions.
Step 3: Learn about linked lists. A linked list is a collection of nodes where each node points to the next one. You can use a linked list to implement a queue by adding new elements at the end and removing elements from the front.
Step 4: Consider the requirements. If you need a fixed size and fast access, an array might be better. If you need a dynamic size and frequent additions/removals, a linked list might be more suitable.
Step 5: Decide which data structure to use based on your needs. Choose an array for simplicity and a fixed size, or a linked list for flexibility and dynamic size.
