Two Pointers Js, Dec 12, 2023 · Studying for the Leetcode style coding interview? This post uses a visual-first approach to help you master the two-pointer technique. Whether you're a beginner or an experience Jan 13, 2022 · Hello, I have been solving all two pointers tagged problems in last 3. Jul 23, 2025 · Now let’s see how the two-pointer technique works. Feb 7, 2022 · In this video, we close out our two-pointer introduction series by applying this pattern to a difficult challenge in order to optimize how we loop over an ar The two-pointer technique I’m referring to here involves using two pointers that start at opposite ends of an array and gradually move towards each other before meeting in the middle. It also allows one to use two different notations referring to the address of the pointer and what is at the address of the pointer. One common application is finding pairs in a sorted array that sum up to a given target. It helps reduce the time complexity of various algorithms and ensures minimal memory usage. io/Code solutions in Python, Java, C++ and JS for this can be found at my GitHub repo here: h Jul 20, 2021 · See how Javascript pointers are implemented, how they work, and learn why pointers in Javascript are the way they are. GitHub Gist: instantly share code, notes, and snippets. Maybe a better way to rephrase your first sentence is instead of "No, JS doesn't have pointers", maybe something like "No, JS doesn't have C-like pointers".
