Removed the mock exercise previews, we're now using the backend exercises for the previews.
| const { lessons, alerts, exercises } = queryData | ||
| const router = useRouter() | ||
| const [exerciseIndex, setExerciseIndex] = useState(-1) | ||
| const [userAnswers, setUserAnswers] = useState<Record<number, string>>({}) |

We store the user's answers on the frontend for now. They go away when you refresh the page. This is good for testing. In the next pull request, we'll get the user's answers from the backend.
| hasPrevious={exerciseIndex > 0} | ||
| hasNext={exerciseIndex < currentExercises.length - 1} | ||
| submitUserAnswer={(userAnswer: string) => | ||
| setUserAnswers({ ...userAnswers, [exercise.id]: userAnswer }) |

Here we add the user's answer to our userAnswers object which stores all the user's answers by exercise ID.
| state={exercisePreview.state} | ||
| problem={exercisePreview.problem} | ||
| moduleName={exercise.moduleName} | ||
| state={exercise.userAnswer === null ? 'NOT ANSWERED' : 'ANSWERED'} |

Right now there are only 2 states, but I think there should be a third state in the future called "ANSWERED INCORRECTLY" or something similar. Maybe we can make "ANSWERED INCORRECTLY" red and then "NOT ANSWERED" can be gray or some neutral color.

How to test:
This pull request doesn't actually save the user's answers. If they refresh the page then their answers are cleared. We will store the user's answers on the backend in a subsequent pull request.
This pull request is a part of #2253 and #2251
