A full-stack AI powered coding practice platform , built using Next.js and Supabase, featuring efficient DSA-based search, and AI-like code evaluation.

✨ Features

• 🔍 Fast problem search using Trie (Prefix Tree)
• 🏆 Leaderboard ranking using Max Heap (Priority Queue)
• will add🧠 AI-style code evaluation using rule-based static analysis
• 📊 Problems stored in PostgreSQL (Supabase)
• ⚡ Modern full-stack architecture with Next.js App Router

🛠 Tech Stack

• Frontend: Next.js (App Router), React, Tailwind CSS
• Backend: Next.js API Routes
• Database: Supabase (PostgreSQL)
• DSA Used: Trie, Heap
• AI Layer: Rule-based evaluator (pluggable for LLMs)

🧠 Data Structures Used

Trie

Used for prefix-based search of problem titles, allowing efficient search in O(L) time.

Heap

Used to implement leaderboard ranking efficiently, avoiding full sorting on every update.
