Here is what I've tried so far:

attempt 1:

1. Minor

2. Critical

3. Distinct

4. Redundant

5. Critical

6. Minor

Total score: 4/6

attempt 2:

1. Minor

2. Critical

3. Distinct

4. Critical

5. Redundant

6. Critical

Total score: 4/6

attempt 3 (I used suggestions from previous question here):

1. Minor

2. Distinct

3. Critical

4. Redundant

5. Critical

6. Minor

Total Score: 2/6

Definition of each level of Redundancy:

Distinct: There are no duplicated attributes or operations. Minor: Any duplication exists in non-adjacent classes. Critical: Siblings have duplicate attributes or operations. Redundant: Multiple instances of redundancy exist in the tree.

Characterize the level of redundancy based on the scenario In the whole inheritance tree, a single duplicate attribute was found in classes on opposite sides of the tree The developer split one class into three: a base class and two derived classes. One member variable is common between the derived classes Though the entire inheritance tree was carefully checked, not a single instance of duplication was found anywhere The developer copied a dozen lines of code from one method and pasted it into another method on a different part of the inheritance tree A private method used to verify the application state is copied into a few dozen classes in an inheritance tree A private method in one class was copied into another class on a different part of the inheritance tree
