Description

The structure includes separate folders for controllers, middlewares, models, and routes.

This PR adds the following routes to our application:

• /signup (POST): Allows users to sign up for the platform
• /login (POST): Allows registered users to login to the platform
• /questions (GET): Returns a list of all available questions
• /submissions/:questionId (GET): Returns a list of submissions for a particular question
• /submissions/:questionId (POST): Allows logged in users to submit a solution for a particular question
