Solution: Find the Length of a Linked List

Explore how to determine the length of a singly linked list by traversing each node and counting. This lesson guides you through an efficient O(n) time and O(1) space solution, helping you build a foundational skill in linked list operations for coding interviews.

We'll cover the following...

Statement

Given the head of a singly linked list, find the length of the linked list.

Constraints:

Let n be the number of nodes in a linked list.

  • 0≤0 \leq n ≤500\leq 500
