What are the basics of data structures?
What are stacks and queues?
Stacks and queues are two fundamental data structures used in computer science. A stack is a collection of elements that supports two basic operations: push (adds an element to the top of the stack) and pop (removes the top element from the stack). A queue, on the other hand, is a collection of elements that supports two basic operations: enqueue (adds an element to the back of the queue) and dequeue (removes the front element from the queue).
