Over a two-month period, MJ Woo developed three core features for the geultto/daily-solvetto repository, focusing on algorithmic problem-solving using Python. He built a backtracking utility to generate all letter combinations from phone digits, enabling predictive text and puzzle features with robust empty-input handling. In subsequent work, he implemented a breadth-first search solution to calculate battle power by grouping soldiers on a grid, and a stack-based solver for daily temperature analysis, optimizing for performance and code clarity. His work demonstrated depth in data structures, recursion, and algorithm design, delivering reusable, production-ready code that streamlines analysis and future development.
January 2025 (Month: 2025-01) – Delivered two feature-oriented solutions in geultto/daily-solvetto with clear business value and solid technical execution. Key features delivered include: Battle Power Calculator (BFS) for Problem 1303, a Python script that identifies contiguous groups of soldiers by color on a battlefield grid using BFS and sums their powers to generate team totals; and the Daily Temperatures Solver using a Stack, a Python solution that computes the number of days until a warmer temperature with a monotonic stack, optimizing performance over a naive approach. Major bugs fixed: none reported this month. Overall impact: provides automation and efficient problem-solving tools that can scale to larger grids and more complex sequences, enabling faster analysis and reusable code for similar challenges. Technologies/skills demonstrated: Python scripting, BFS, monotonic stack algorithms, data structures, algorithm optimization, code readability and maintainability. Business value: reduces manual analysis time for battlefield power calculations and accelerates problem-solving workloads, supporting faster decision-making and reusable patterns for future coding tasks.
