What is underflow and overflow in link list with example?

Underflow in a linked list occurs when an attempt is made to remove an element from an empty list, resulting in an error since there's nothing to remove. For example, if a linked list is empty and a deletion operation is attempted, it triggers an underflow condition. Overflow, while less common in linked lists since they can dynamically grow, can refer to a scenario where the linked list exceeds a predefined limit (like a maximum size), often encountered in linked list implementations with a fixed size, such as a bounded queue. For instance, if a linked list is designed to hold only 10 elements and a push operation is attempted when it already contains 10 elements, an overflow occurs.
