Fast & Slow Pointers vs Two Pointers vs Sliding Window

In this post I compare Fast & Slow Pointers, Two Pointers, and Sliding Window patterns: how each pattern works, how pointers move, their key differences, and how to recognize which approach to use in LeetCode problems and coding interviews.

Fast & Slow pointers pattern: Tortoise and Hare technique for coding interview

The Fast & Slow pointers pattern uses two pointers moving at different speeds to detect cycles, find middle elements, and solve Linked List and sequence problems efficiently.
