Then, you move the end marker to In the world of coding interviews and algorithmic problem-solving, the sliding window technique stands out as a powerful and efficient approach for tackling a wide range of problems. Usually, the technique helps us to reduce the time complexity from to . Oct 16, 2022 · The sliding Window Algorithm helps us solve many simple and complex coding problems with an optimized approach and lesser time complexity. It involves selecting a fixed-size subset, or "window," from a larger dataset and moving this window through the dataset in a step-wise fashion. Oct 16, 2022 · When we solve problems using this Sliding Window algorithm we try to create or find fixed-size or variable-size windows (here window is nothing but a subarray or substring) which satisfies the given condition of the problem and then we keep sliding the window by one unit to cover next subarrays. Sep 2, 2025 · Sliding Window Technique is a method used to solve problems that involve subarray or substring or window. The condition to use the sliding window technique is that the problem asks to find the maximum (or minimum) value for a function that calculates the answer repeatedly for a set of ranges from the array. 22 hours ago · Struggling with 'Longest Substring'? The Sliding Window pattern is easy if you follow this step-by-step 'Expand-Contract' framework. What is the Sliding Window Algorithm? 1. Learn how to optimize from O(n²) to O(n) time complexity. . In most cases, we use the sliding window algorithm to reduce the use of nested loops and the repetitive work that we do while solving any problem. Whether you’re preparing for technical interviews at top tech companies or simply looking to enhance your programming skills, understanding and mastering sliding window algorithms can give you a significant edge Mar 18, 2024 · The main idea behind the sliding window technique is to convert two nested loops into a single loop. At first, both markers are at the very first item. In the world of coding interviews and algorithmic problem-solving, the sliding window technique stands out as a powerful and efficient approach for tackling a wide range of problems. Fixed-Size Sliding Window Algorithm. Sep 2, 2025 · Sliding Window Technique is a method used to solve problems that involve subarray or substring or window. Jun 18, 2025 · What is the sliding window algorithm? The sliding window algorithm is a technique used to efficiently find subarrays or substrings that meet specific conditions, such as maximum sum, fixed-length averages, or unique character constraints in arrays, lists or strings. Tagged with slidingwindow, leetcode, algorithms, interviewprep. See the problem statement, manual and code solutions, and visual explanation of the sliding window approach. Through practical examples, we will guide you on how and when to apply this powerful technique. Learn key patterns, example problems, and real-world applications in 2025. Jan 11, 2024 · Learn how to use the sliding window technique to find the maximum sum of a sub-array of size k in O(N) time complexity. Instead of repeatedly iterating over the same elements, the sliding window maintains a range (or “window”) that moves step-by-step through the data, updating results incrementally. Then, you move the end marker to Mar 18, 2024 · When dealing with problems that require checking the answer of some ranges inside a given array, the sliding window algorithm can be a very powerful technique. Learn how to optimize from O (n²) to O (n) time complexity. May 12, 2025 · Master the sliding window technique with this guide featuring Python, Java, and C++ code examples. Jun 18, 2025 · The sliding window algorithm is a technique that streamlines nested loops into a single loop to process contiguous elements in arrays or strings, reducing time complexity and improving efficiency for problems like max sum, averages or pattern matching. Jul 23, 2025 · Sliding window problems are computational problems in which a fixed/variable-size window is moved through a data structure, typically an array or string, to efficiently process or analyze the continuous subsets of elements. Jun 25, 2024 · To use this method, you need two markers: one to show where the window starts and one to show where it ends. In this tutorial, we’ll explain the sliding window technique with both its variants, the fixed and flexible window sizes. Feb 8, 2025 · In this article, we will take a deep dive into the sliding window algorithm, exploring both fixed-length and variable-length solutions. Jan 11, 2024 · What is the Sliding Window Technique? The sliding window technique is an algorithmic approach used in computer science and signal processing. 2. Mar 18, 2024 · When dealing with problems that require checking the answer of some ranges inside a given array, the sliding window algorithm can be a very powerful technique. Namely, if these Understand the sliding window technique used in algorithms to solve problems efficiently.
