Problem: Length of Linked List Given the head of a singly linked list, return the number of nodes in the list. Input Format: The input will be given as the head of a linked list. Output Format: Return a single integer, the total number of nodes in the linked list. Examples: Example 1: Input: 0 1 2 Output: 3 Explanation: The list has a total of 3 nodes, so its length is 3. Example 2: Input: 2 5 8 7 Output: 4 Explanation: The list has 4 nodes, hence the length of the list is 4.
