📦 Warehouse Optimization System

An intelligent, web-based system designed to optimize warehouse storage using the 0/1 Knapsack Algorithm and hashing techniques for efficient product placement and retrieval. Built with Node.js, Express, PostgreSQL, and EJS, this platform ensures maximum space utilization and fast inventory access.

🚀 Features
