Two Pointer Pattern Explained, Schedule a 1:1 session with me: https://topmate. I’ll do my best to explain it in a simple way and leave you with To change the tempo of individual patterns, edit the Piano roll data and or number of Stepsequencer steps for that Pattern so the new tempo is achieved. Explain your approach: Clearly explain the intuition behind using two pointers and how they help solve the problem efficiently. How It Works Usage: Two pointer approach can be used when you want to process two elements in a single iteration or determine a type of pattern. We will start with a brute force solution Can you solve this real interview question? Two Sum II - Input Array Is Sorted - Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order, find two numbers such that they add up to a specific target number. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. c. 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. (Not talking about linked list fast/slow pointer) Greedy algorithms are hard to identify and prove. L1. It helps solve problems that involve searching, sorting, or traversing arrays, strings, or linked lists in an efficient way. Two Pointers || 25 DSA Patterns || New & Easy way to Master DSA || Crack DSA round|| Crack FAANG A curated list of leetcode questions grouped by their common patterns Jul 23, 2025 · 5. Learn all variants, when to use each pattern, complete templates in multiple languages, and a systematic approach to solve any two pointers problem. The Two Pointers pattern is a coding technique used to solve problems involving arrays or sequences by using two pointers that move through the array simultaneously. Whether it’s flashcards, essays, or topics, Cram. This is because two pointers can easily track the start and end of the window. To set the Time signature use the Project General Settings. 5 months, and wanted to share my findings/classifications here. Jul 26, 2025 · Two pointers is a pattern where you use two indices (or “pointers”) to traverse an array — either from both ends or from the same direction — to solve a problem more efficiently than brute force. The two pointer and sliding window techniques are widely used algorithmic approach in computer science and programming. 53K subscribers Subscribe Master DSA Patterns: https://algomaster. Includes detailed explanations, problem links, and clear strategy breakdowns for both fixed-size and variable-size window problems. Let Sep 3, 2020 · Let's learn about the Two Pointers technique to algorithm templates and two main variations of this technique. If you are preparing for. Perfect for coding interview preparation.
