Erica and Bob participate in a friendly Hackathon that allows each to solve one question a day out of the three offered. There will be one easy, one medium and one hard question, with points awarded based on difficulty. The participant can also choose to skip a question. The winner is the one with the highest score at the end of the competition based on the following scale. In case of a tie, the person who solves the most hard problems wins. If it's the same, the one with more medium problems wins; otherwise, the one with more easy problems wins. If they both have the same score and the same number of problems at the same difficulty level, then it's a tie.
