Pull Request Overview
This PR introduces a two-pointer technique implementation for linked lists, providing a reusable template for common linked list operations using fast and slow pointer patterns (Tortoise and Hare algorithm).
Key Changes:
- Adds
two_pointer_technique.rimplementing cycle detection, middle node finding, and nth-from-end node retrieval - Updates
DIRECTORY.mdto include the new algorithm in the linked list algorithms section
