In this post, you will be going through 13 problems which kind of sets the tone for the other In essence, the Two Pointer technique aims to address problems where identifying pairs, subarrays, or specific patterns within arrays or linked lists is crucial. Once the array is sorted then we can use this approach by keeping one pointer at the beginning (left) and another at the end (right) of the array. For these questions, each pointer represents where the next element belonging to that region should go.
