E-Commerce DS: SmartCart & B+ Tree Indexing 🛒⚡

E-Commerce_DS is an exploration of high-performance backend algorithms applied to retail systems. The repository features SmartCart, an implementation that utilizes optimized data structures—specifically a B+ Tree—to handle fast product lookups, range queries, and dynamic catalog indexing.

🚀 Key Features

• B+ Tree Indexing Engine: Custom implementation of a B+ Tree tailored for high-fanout indexing of product inventories, mimicking database mechanics.
• SmartCart Simulation: Algorithmic backend workflows illustrating automated product retrieval, sorting, and efficient data mutations within a shopping cart context.
• Optimized Search Operations: Supports exact match lookups ($O(\log n)$ efficiency) alongside fluid range queries for category filter simulations.
• Modular Full-Stack Blueprint: Combines a clean Python backend infrastructure with interactive frontend access points.
