An array is a data structure that stores a collection of elements of the same type. Different ways to sort arrays include bubble sort, merge sort, and quick sort.

Stacks and queues are data structures used to store and retrieve data in a specific order.

• Stacks are Last-In-First-Out (LIFO) data structures where the last element added is the first one to be removed. Example: a stack of plates.

• Queues are First-In-First-Out (FIFO) data structures where the first element added is the first one to be removed. Example: a queue of people waiting in line.

• Both can be implemented using arrays or linked lists.
