        Long questionUpvoteCount = questions.stream().map(Question::getUpvoteCount).reduce(0L, Long::sum);
        Long questionDownvoteCount = questions.stream().map(Question::getDownvoteCount).reduce(0L, Long::sum);
        List< Answer> answers= answerRepository.findByAnsweredBy(user.getId());

        Long answerDownvoteCount = answers.stream().map(Answer::getDownvoteCount).reduce(0L, Long::sum);
        return (questionCount * 10 + answerCount * 15 + questionUpvoteCount * 25 + answerUpvoteCount * 30) - (questionDownvoteCount*10 + answerDownvoteCount*15);

According to our requirements,

Reputation Points: Reputation Points is a number associated with a Profile, defined as the sum of Ratings of the Profile Owner’s Questions and Answers.

This PR weighs upvotes more than downvotes. Can we instead weigh them the same so that one upvote cancels one downvote and vice versa?
