Cycle Detection | HackerRank Solutions. Problem Statement : A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0.
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return . Otherwise, return . Example.

#using Floyd’s Tortoise and Hare cycle-finding algorithm - Our slow pointer moves forward 1 node at a time, #and our fast pointer moves forward 2 nodes at a time. If at any point in time these pointers refer to the same object,
See the original problem on HackerRank. Solutions. An efficient solution is based on the “two pointers idiom”. We traverse the list using two pointers that we’ll refer to as fast and slow. Our slow pointer moves forward 1 node at a time, and our fast pointer moves forward 2 nodes at a time. If at any point in time these pointers refer to ...
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. For example, in the following graph there is a cycle formed when node points back to node . Function Description. Complete the function has_cycle in the editor below.
Cycle Detection: """. Detect a cycle in a linked list. Note that the head pointer may be 'None' if the list is empty. A Node is defined as: class Node(object): def __init__(self, data = None, next_node = None): self.data = data. self.next = next_node.
