A stack is a linear data structure that follows the LIFO (Last In First Out) principle, meaning the last element added to the stack is the first one to be removed.
Both insertion (push) and deletion (pop) occur at a single end, known as the "top" of the stack.
Push: Adds a new element to the top of the stack. If the stack is full, this causes a Stack Overflow.
Pop: Removes and returns the top element from the stack. If the stack is empty, this causes a Stack Underflow.
