Stack
A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. Elements are added (push) and removed (pop) from the top, making it ideal for tasks like expression evaluation, backtracking and function call management. Common implementations include arrays and linked lists for efficient data handling.
