Contributed a series of algorithmic solutions to the DaleStudy/leetcode-study repository over two months, focusing on efficient Java implementations for common coding interview problems. Developed sixteen features covering array manipulation, dynamic programming, backtracking, and data structures such as HashMap and PriorityQueue. Solutions included duplicate detection, two-sum, 3Sum, maximum subarray, and combination sum, each emphasizing time and space efficiency, edge-case handling, and clear documentation. Applied techniques like sorting, recursion, and two-pointer methods to ensure robust, reusable code. All features were delivered with clean commit histories and passing tests, expanding the repository’s coverage for interview preparation and algorithm study resources.

9 Commits • 8 Features
Aug 1, 2025Monthly summary for 2025-08 (DaleStudy/leetcode-study). Delivered a focused set of high-value algorithm implementations with clean, testable code and clear commit history. Key features delivered include 3Sum solution, BST validation, Decode Ways DP, Kadane's Algorithm for Maximum Subarray, and a Combination Sum Solver, reflecting strong coverage of array problems, data structures, DP, and backtracking. No major bugs reported this month; all changes merged with tests passing. Impact includes expanded algorithm coverage for interview prep tooling, improved code reuse across problems, and tighter performance characteristics (e.g., O(N) Kadane, efficient backtracking with pruning). Technologies/skills demonstrated include sorting and two-pointer techniques, recursion, dynamic programming, backtracking, preprocessing for string problems, and concise solution design with clear commit history.
