Fast and Slow Pointers

I will cover all the LeetCode Patterns for coding Interviews mentioned by a few folks. I'll write the code using C#. Today's post is related to Slow and Fast pointer LeetCode Patterns for Coding Interviews.

The?Fast & Slow?pointer approach, also known as the?Hare & Tortoise algorithm, is a pointer algorithm that uses two pointers which move through the array (or sequence/LinkedList) at different speeds. This approach is quite useful when dealing with cyclic?LinkedLists?or arrays.
