Q1. Find the loop in a circular linked list
Ans. 
To find the loop in a circular linked list, we use Floyd's cycle-finding algorithm.
• Initialize two pointers, slow and fast, both pointing to the head of the linked list.

• Move slow pointer by one node and fast pointer by two nodes in each iteration.

• If there is a loop, both pointers will eventually meet at some node.

• To find the starting point of the loop, reset the slow pointer to the head and move both pointers by one nod
