🧠 LeetCode Practice

Daily/near-daily problem-solving practice across SQL and Python — building strong fundamentals one problem at a time, from basics up through applied concepts.

Each problem folder — in either language — contains:

• 📘 README.md — problem summary, explanation, concepts, and key learnings
• 💻 solution.sql or solution.py — the accepted solution

🗂️ Folders

SQL/

Following LeetCode's SQL 50 study plan. Covers filtering, joins, aggregation, subqueries, and (up next) CTEs and window functions. MySQL syntax throughout.

Python/

Fundamentals-first practice via LeetCode's Programming Skills study plan, moving toward light OOP (Design-tagged problems) and applied data structures as the course progresses.

🎯 Goal

Build strong fundamentals in both SQL and Python through consistent, deliberate practice — prioritizing understanding and retention over speed or volume.
