Q2. Detect a loop in linked list
Ans. 
Loop in linked list can be detected using Floyd's cycle-finding algorithm.
• Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.

• If there is a loop, the faster pointer will eventually catch up to the slower pointer.

• If there is no loop, the faster pointer will reach the end of the list.

• Time complexity of this algorithm is O(n) and space complexity is O(1).
