During December 2024, Dale contributed to the DaleStudy/leetcode-study repository by developing three algorithmic features focused on classic coding interview problems. Dale implemented an Anagram Validation System in Java using a sorting-based approach to efficiently determine string equivalence, and created a dynamic programming solution for the Climbing Stairs problem, optimizing for O(N) time and space complexity. Additionally, Dale delivered Two Sum and ThreeSum solutions, leveraging hash maps and two-pointer techniques for array manipulation. All features were accompanied by thorough documentation and minor formatting improvements, demonstrating strong skills in Java, data structures, and algorithm design while enhancing maintainability and onboarding for future contributors.
