Strengths:

• The student provides multiple solutions, demonstrating a deep understanding of the problem.
• The code is well-commented and organized, making it easy to follow.
• The test cases are thorough and cover edge cases, ensuring robustness.

Areas for Improvement:

• The first method (indegrees/outdegrees) could be simplified by combining the indegrees and outdegrees calculations into a single loop, as done in the second method.
• The third method's explanation could be clearer about why the initial candidate selection works and why the subsequent checks are necessary.
