Two Pointer Technique Javascript, Jan 3, 2022 · What is a pointer? In a for loop, the "i" value is the pointer i. The Two-Pointer Technique is an invaluable tool in the toolbox of any programmer, whether you're preparing for an interview or building complex, real-world applications. Whether you're a beginner or an experience. We need to find pairs/triplets or process subarrays without restarting from scratch. It is also much faster than using two for loops as both pointers can move through the array at the same time (don't quote me on this The two pointer technique is a near necessity in any software developer's toolkit, especially when it comes to technical interviews. Apr 11, 2023 · To implement the sliding window technique in JavaScript, you can use two pointers and a loop that iterates over the collection. Need to calculate the sum of the elements in the array at these two positions of the pointers. Jul 23, 2025 · Instead of brute force, a more better approach" Two-Pointer Technique" can be used. Where can I practice two pointer problems? Jun 9, 2020 · The idea of using two pointers here is to point at two different numbers at the same time. The main idea is to use two indices (pointers) that Master Data Structures & Algorithms for FREE at https://AlgoMap. We have explained how to use it in JavaScript. In the examples below, two pointers are used to accomplish a variety of tasks. You can also use additional variables to keep track of the current window and the maximum value. Apr 29, 2025 · Master the Two Pointers Pattern in JavaScript by Reversing a String Reversing a string using the two pointers pattern is an efficient and widely used approach with a time complexity of O (n). By utilizing two pointers either moving towards each other or in the same direction, we can reduce the time complexity of many problems from O (n2) to O (n) or O (nlogn). If you haven't applied two-pointer techniques in your problem-solving process, I hope this example boosts your confidence in coming up with more performant algorithm solutions. When to Use the Two Pointer Pattern The Two Pointer Pattern is helpful when you need to perform a search to find a pair of numbers that meet a certain condition within a sorted Take your coding skills to the next level with our latest video tutorial on two pointers algorithms in JavaScript. Watch now Oct 17, 2021 · The Two-Pointer Technique In this second installment of my Algorithms and Data Structures Series, I explain a very common technique used in search algorithms: the two-pointer technique. It is commonly used when: Data is sorted or the problem has sequential properties. Sliding window is a variation of the two pointer method where one pointer represents the start of the window and the other represents the end. Nov 30, 2018 · This is another one of the most commonly used interview question solution techniques.
