Question
What happens when you try to pop an element from an empty stack? The program crashes. The top element is returned and removed. An error message is displayed. Nothing happens.
Solution
When you try to pop an element from an empty stack, an error message is displayed. This is because there are no elements to remove from the stack. The stack is a data structure that follows the Last-In-First-Out (LIFO) principle, meaning the most recently added element is the first one to be removed. If there are no elements in the stack, the operation cannot be performed, and typically, an error or exception is thrown.
