RedSet creates a beneficial environment for learners that includes topic wise problems with solution, notes section where user can keep notes or templates, notify about running and upcoming contest of groups where user is joined, leaderboard and activity, and the exclusive feature LatticeLine, that includes compiler, groups feature (Individual can create or join groups. The teachers of every group can make announce, assignment - like Google Classroom and contest - like an Online Judge.)

Configuration

You can run our project in your system by cloning the project. Run git clone https://github.com/hasnat0006/RedSet in your terminal. Before run, delete RedSet/target (if found) and create a database named lattice in your localhost mysql server. Run CREATE DATABASE lattice;. Then run the given sql script for the full database lattice.
