Q1. Detect and remove loop in a single linked list
Ans. 
To detect and remove a loop in a single linked list, we can use Floyd's Cycle Detection Algorithm.
• Use two pointers, slow and fast, to detect a loop in the linked list.

• Move slow pointer by one step and fast pointer by two steps. If they meet at some point, there is a loop.

• To remove the loop, find the start of the loop using Floyd's Algorithm and then remove the loop by breaking the link.

Q2. Clone a linked list with random and next pointer
Ans. 
Cloning a linked list with random and next pointers involves creating a deep copy of the original list while maintaining the connections between nodes.
• Create a mapping of original nodes to their corresponding new nodes

• Iterate through the original list and create new nodes with the same values

• Update the random and next pointers of the new nodes based on the mapping created
