Challenge: Detect Loop in a Linked List
Loops in linked lists can be dangerous. Now, you'll create an algorithm to detect them.
We'll cover the following
Problem Statement
By definition, a loop is formed when a node in your linked list points to a previously traversed node.
You must implement the detectLoop()
function which will take a linked list as input and deduce whether or not a loop is present.
Input
A Singly linked list.
Output
Returns True
if the given linked list contains a loop. Otherwise, it returns False
Sample Input
Linkedlist = 7->14->21->7 // Both '7's are the same node. Not duplicates.
Sample Output
True
