Welcome to My Advent of Code 2025 Solutions

Welcome! 👋
This blog documents my personal solutions to the 2025 Advent of Code challenge.

Advent of Code is a series of daily programming puzzles that reward careful problem analysis, clean implementation, and—often—rethinking early assumptions. This site is both a solution archive and a learning space.

Purpose of This Blog

The goal of this forum is not just to present working answers, but to:

• 📘 Explain problem-solving approaches and design choices
• ❓ Ask and answer questions about tricky parts of the puzzles
• 🐞 Raise issues, edge cases, or performance concerns in the solutions
• 🔄 Explore alternative implementations and optimizations
• 🧠 Turn Advent of Code 2025 into a shared learning experience

Some solutions may evolve over time as better ideas emerge or mistakes are discovered.

What You’ll Find Here

• Daily write-ups for Advent of Code 2025
• Clear explanations alongside code
• Notes on pitfalls, false starts, and Part 2 surprises
• Performance and algorithmic tradeoffs
• Occasional refactors and postmortems

Unless otherwise noted, solutions favor clarity first, followed by efficiency where it matters.
