Can you read the following code and try to complete the TODO in class HomogeneousCriterion(Criterion), class HeterogeneousCriterion, and class LonelyMemberCriterion. If there is any part that you are unsure about, mark it out if possible. Please upload answer in screenshots or in proper indentation. At last, please do not just copy a wrong answer from others.

1. Can add any private attribute or methods if needed

if you add any private abstract method to Criterion class and other class all inherit from this you have to implement all abstract method!

2. Can inherit from other class in file instead of Criterion if that is easier

3. try to not have loop if layers more than 4. example: (if:(if:(for:(if:...))))

4. can add a __eq__ to compare if needed!

Thank you so much!

Explanation:

1. HomogeneousCriterion: looks at the similarity, add the similarity of every two answers of all answers to take the average

2. HeterogeneousCriterion: 1 - HomogeneousCriterion's result. (Inheritance!!!)

3. LonelyMemberCriterion: if answer contains any unique answer( 0or 1) if there exists only one answer that is uniqueit is 0

if there exists two answerssame then no uniquenot the same then it is unique

2 2 4 4 4, not uniqueso it is 1

2 2 4 4 4 3, one uniqueso result is 0

u can still make changes to class Criterion above if needed
