- In C++ Question 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. Example: head refers to the list of nodes 1 → 2 → 3 → 1 → NULL. There is a cycle where node 3 points back to node 1, so return 1. Function Description: Complete the has cycle function provided in the moodle assignment folder. It has the following parameter: • SinglyLinkedListNode pointer head: a reference to the head of the list. Returns: • int: 1 if there is a cycle or 0 if there is not. Note: if the list is empty, head will be null. Input Format: The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity.
