Given a singly linked list. The task is to find the length of the linked list, where length is defined as the number of nodes in the linked list.
Example 1:
Input:
LinkedList: 1->2->3->4->5
Output: 5
Explanation: Count of nodes in the
linked list is 5, which is its length.
Example 2:
Input:
LinkedList: 2->4->6->7->5->1->0
Output: 7
Explanation: Count of nodes in the
linked list is 7. Hence, the output
is 7.
Your Task:
Your task is to complete the given function getCount(), which takes a head reference as an argument and should return the length of the linked list.

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
