Two pointer technique in JavaScript

Introduction

The two pointer technique is one of the tools to solve competitive programming and to solve technical interviews. We have explained how to use it in JavaScript.

The pattern in two pointer is that by processing two elements over a single loop we can improve the time and space complexity. That is why it is more efficient than the naive approach( Brute force approach ) which processes a single element per loop.

we can apply this approach either on arrays or linked list to find sub elem...
