What are some common problems with linked lists?

Some common problems include reversing a linked list, detecting cycles, and merging two sorted linked lists.

Can you explain how to reverse a linked list?

To reverse a linked list, you can iterate through the list, changing the next pointers of each node to point to the previous node.

What is cycle detection in linked lists?

Cycle detection is identifying if a linked list has a loop. The Floyd’s Tortoise and Hare algorithm is commonly used.

How do I merge two sorted linked lists?

You can merge two sorted linked lists by comparing the nodes and linking them in order until one list is exhausted.
