Hoonji Choi
During July 2026, contributed to the DaleStudy/leetcode-study repository by developing three new features focused on algorithmic problem-solving and code maintainability. Implemented a frequency-map based anagram solver in Java to ensure accurate string validation and data integrity. Added an iterative dynamic programming solution for the Climbing Stairs problem, documenting the recurrence relation and refactoring obsolete files to enhance maintainability. Expanded the repository’s learning resources by introducing four additional Java algorithms, including solutions for Valid Palindrome, Number of 1 Bits, Combination Sum, and Decode Ways. Work emphasized algorithms, dynamic programming, and code formatting, with no major bug fixes during this period.
