In this tutorial, we’ll discuss the two-pointer approach for solving problems involving arrays and lists. This technique is an easy and efficient way to improve the performance of our algorithm. 2. Technique Description In many problems involving arrays or lists, we have to analyze each ...
In the world of algorithm design and problem-solving, the two-pointer technique stands out as a powerful and widely utilized strategy. With its application extending to arrays, linked lists, and strings, this approach has proven its efficacy in reducing time complexity and, in certain cases...

If we think similarly as we solved in the two sum problem, what we need to sort the arrays. We started from the beginning of one array and the end of another array. That was our two-pointer algorithm where we traversed the pointers based on the sum of the current ...
