Find the town Judge (Problem1.cs)

Strengths:

• Clear and concise explanation in comments
• Clean variable naming convention
• Correct index handling (0-indexed array with proper conversions)
• Optimal time and space complexity

Areas for Improvement:

• Consider adding edge case handling for n=1 (when there's only one person, they are trivially the town judge since they trust nobody and nobody trusts them). Currently, with an empty trust array, the loop would correctly not find any match and return -1, but explicitly handling n=1 could make the intent clearer.

Overall, this is a solid implementation that matches the reference solution in both correctness and efficiency.

VERDICT: PASS

Ball in the Maze (Problem2.cs)

Strengths:

1. Clean and well-commented code that clearly explains the approach
2. Correct implementation of the rolling ball mechanics
3. Proper use of BFS with visited marking
4. Good variable naming and code structure
5. Correct handling of boundary conditions

Areas for Improvement:

1. The destination check could be done before marking as visited to potentially save one queue operation, but this is a minor optimization.
2. Consider using a separate visited array instead of modifying the input maze, as modifying the input might not be desirable in all scenarios.

Overall, this is a solid solution that correctly solves the problem with appropriate time and space complexity.

VERDICT: PASS
