Question

For linked list questions assume the following Linked list class definition: struct Node { int value; Node* next; Node(int num = 0) : value(num), next(nullptr) {} }; class LinkedList { Node* head; public: LinkedList() : head(nullptr) {} // other member functions }; Linked List Cycle Write a member function of the class LinkedList that returns true if a cycle exists in the linked list, false otherwise. • Do not assume the existence of any other functions to use. • Return false if the list is empty. What does "cycle" mean? The singly linked list is a linear sequence. That is, starting with the head, if we traverse each node, no node will be visited twice. However, if the next pointer stored within a node points to an already traversed node, it will form a cycle (see example below). Example For the list head 18 7 15 27 The function should return true.

Linked List Cycle
Write a member function of the class LinkedList that returns true if a cycle exists in the
linked list, false otherwise.
• Do not assume the existence of any other functions to use.
• Return false if the list is empty.
What does "cycle" mean? The singly linked list is a linear sequence. That is, starting with
the head, if we traverse each node, no node will be visited twice. However, if the next
pointer stored within a node points to an already traversed node, it will form a cycle (see
example below).
Example
For the list
head
18                  7                  15                  27
The function should return true.
