Loop in a linked list can be found 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 in the linked list, the two pointers will eventually meet.

• To detect the starting point of the loop, reset one of the pointers to the head and move both pointers at the same speed.

• The point at which they meet again will be the starting p
