Comprehensive guide to install and configure Syncthing on a Linux server, ensuring secure and efficient file synchronization.

Understanding common problem-solving patterns is key to tackling a wide range of coding challenges on LeetCode. In this post, we introduce 15 widely used patterns, explain how they work, and provide links to deeper explanations. Learn how to use these patterns to solve complex problems and enhance your algorithmic skills.

The Fast and Slow Pointers (Hare and Tortoise) pattern helps detect cycles in data structures like linked lists efficiently. Learn how to implement it in Java with practical examples and understand the time and space complexity trade-offs.

Learn how the Sliding Window pattern optimizes solutions to problems involving subarrays or substrings. This post explains the concept, gives a practical example with Java code, and compares brute force vs. optimized approaches, complete with Big O analysis.

The Two Pointers pattern optimizes solutions to problems involving sorted arrays, pairs, or partitioning. Learn how to implement it in Java with a practical example, comparing brute force vs. optimized approaches, and understand the Big O analysis.
