Aug 1, 2025Month: 2025-08 Overview: Delivered a targeted set of Python algorithmic solutions in the ai-kmu/etc repository, expanding the reusable problem-solving toolkit and reinforcing clean, edge-case aware implementations. One convex-hull attempt remained incomplete, and there were no major production bug fixes this month. Emphasis was placed on clear commit tracing, in-place algorithms, and solutions suitable for quick integration into internal tooling or interview prep. Key achievements and impact: - Ladder Problem Solver: Implemented a solver to compute the minimum number of rungs to add to a ladder given existing rungs and a maximum allowed rung distance (commit ff34c5aadfb3b1ced010270f24c9963dc2be1a5e). - Perfect Number Utility: Built an efficient perfectly-number check using divisor summation up to sqrt(n) with proper edge-case handling for n=1 (commit da7ae0ef7b85db570abd30bfe289b991de0d1e99). - Baseball Game Scoring Solution: Added Solution.calPoints to process a sequence of operations for scoring, including new scores, doubling, summing last two, and invalidations (commit 192209ab54cffcf1fd30ca436af50f941bc1e2b4). - Remove Duplicates from Sorted Array: Implemented in-place removal of duplicates using a two-pointer technique, returning the new length after overwriting duplicates (commit e256c79cd55b026399d4673a05becab0fae4c27d). - Bulb Switcher II Solution: Implemented a solver to determine the number of possible bulb states after a given number of presses under the defined rules (commit 22e5e262a5d0fc6ea439454f2aa97624a6ca9521). Major bugs fixed: - None reported as fixed this month. A known, incomplete Erect the Fence (convex hull) solution was identified and logged for follow-up (commit 9d60188e2ce10f384db0c402d16daed1360cd004). Overall impact and business value: - Accelerated capability to solve common algorithmic tasks with clean, reusable Python modules, enabling faster onboarding for code challenges and internal tooling. - Improved code quality through consistent structure (Junghyeon.py) and explicit edge-case handling, supporting reliability in future deployments and demos. - Enhanced maintainability through clear commit traces and documented intent, aiding future reviews and knowledge transfer. Technologies and skills demonstrated: - Python programming, algorithm design, and data structures (e.g., two-pointer technique, sqrt-based divisor summation). - In-place array manipulation and robust edge-case handling. - Problem-solving patterns applicable to coding interviews and technical assessments.

May 1, 2025May 2025 monthly summary focusing on key accomplishments for the ai-kmu/etc repository. Delivered a BFS-based solver to compute the minimum number of turns required to reach a target lock combination from '0000', with dead-end avoidance and handling of cases where the starting combination is a dead end. Implemented core logic in a dedicated module for clarity and reuse, enabling straightforward extension to additional configurations. This work reduces manual trial-and-error effort and provides a reliable, scalable foundation for lock puzzle solving in automation pipelines.
