Arrays: Arrays are fixed-size collections that store elements of the same type sequentially in memory. They offer fast access but limited flexibility in terms of resizing.
Linked Lists: Linked lists consist of nodes connected through pointers where each node holds a value and a reference to the next node. They allow dynamic memory allocation but have slower access times compared to arrays.
Stacks: Stacks follow the Last-In-First-Out (LIFO) principle where elements can only be inserted or removed from one end called the top. They are useful for tracking function calls or undo/redo operations.
