During a two-month period, Cod3holic developed and stabilized a suite of algorithmic solutions for the DaleStudy/leetcode-study repository, focusing on dynamic programming, data structures, and binary search in C++. Cod3holic implemented features such as Two Sum, House Robber, and Combination Sum, while also addressing critical bugs to improve correctness and maintainability. The work included enhancing documentation and standardizing code practices, which streamlined onboarding and future contributions. In December, Cod3holic delivered a reusable Core Algorithms and Data Structures Library, adding foundational algorithms like merge two sorted lists and coin change, further strengthening the repository’s scalability and code quality.
