During February 2026, Anjali Sahni focused on improving the reliability of LeetCode problem solutions in the doocs/leetcode repository. She addressed a bug in the Lemonade Change Problem (LC860) by correcting the initial tracking value for ten-dollar bills, ensuring accurate handling of cash transactions and reducing the risk of edge-case failures. Her approach involved careful debugging and code review, leveraging C++ for solution correctness and algorithm development. Although no new features were introduced, her work enhanced the maintainability and robustness of the codebase, demonstrating disciplined problem solving and effective use of git for traceable, regression-test-ready changes.
