This repository contains a collection of SQL challenges that I've completed from HackerRank. These challenges help me sharpen my problem-solving skills and deepen my understanding of algorithms and programming.
The challenges are completed using MySQL & PostgreSQL.
This repo contains my own solutions, with links to the problem statements for reference.
It includes folders for each platform. For now, only HackerRank is included, with plans to expand in the future.
Each challenge is contained in its own folder. Every folder includes:
- a
README.mdexplaining the task, skills/concepts, and approach - a
solution.sqlfile containing the SQL solution
The difficulty of each challenge is indicated in the Markdown title.
