Apr 1, 2025April 2025 monthly summary for the coding-test-certification repository. Delivered a cohesive Coding Challenge Solutions Suite that aggregates seven algorithmic problem solvers (number guessing, balloon factory simulation, unit movement, number-to-word conversion, Easy Stair Number, Weapon Engineering, Tree Diameter) into a single, reusable framework. Achieved steady, milestone-driven progress with weekly submissions from Week 5 through Week 8, ensuring incremental improvements and maintainable code. No major bugs reported this month; the focus was on delivering the feature suite and stabilizing the integration points. This work positions the repository for rapid certification readiness and scalable future enhancements.
