      ".read":true,
      ".write":true
    },
    "users": {

Adding Featured Problems

cs-points allows you to feature problems and assign weight to the problem. To do this, go to the Firebase console and navigate to the database tab.

This is where you would add your featured problems. (Any collapsed item is automatically generated by the app)

To add a featured_problem click on the plus button on the root parent of the heirarchy

Then type featured_problems in the Name field and press the + button on the right

Type a Unique ID for the problem in the Name field and press the plus button to add the child properties

Featured problem properties:

• unique ID
  • name - The exact name of the problem that is shown on UVa
  • url - The UVa URL of the problem
  • weight - The number of points given to the user if they solve the problem
