Jan 10, 2026 · If you're grinding for Amazon SDE-1 (or any FAANG-level role), Linked Lists are a staple in interviews—especially for pointer manipulation, cycles, and re-linking problems. Link for other im Level up your coding skills and quickly land a job. Example: Detecting loop in a linked list, checking palindrome in arrays, strings, and linked list, reversing a string or a linked list, two sum problem, finding the middle of a linked list, etc. Two-Pointer Technique: Use two pointers to move across the Problems on 2 Pointers are a test of your observation skills and how well you can deduce patterns. If the sum of the two numbers pointed by the two pointers is smaller than the target sum, this means that we need a pair with a larger sum. Sep 15, 2025 · The Two-Pointers Technique is a simple yet powerful strategy where you use two indices (pointers) that traverse a data structure—such as an array, list, or string—either toward each other or in the same direction to solve problems more efficiently Jul 8, 2025 · By using two pointers to traverse data structures (typically arrays or strings), we can solve complex problems with optimal time complexity, often transforming O (n²) solutions into O (n) Overall, the two pointers technique is a useful approach for solving specific types of problems that involve iterating through a data set in a controlled way, such as in pattern matching, data analysis, and statistics. Iterating two monotonic pointers across an array to search for a pair of indices satisfying some condition in linear time. What You’ll Learn in This Video: What is the Two Sep 23, 2025 · Learning DSA Two Pointers Pattern using Java One of the most elegant tricks in problem-solving is the Two Pointers technique.
