Strengths:

1. Both solutions are correct and efficient, demonstrating a good understanding of the problems.
2. The use of in-place marking for state transitions in "Game of Life" is a clever optimization.
3. Code is well-structured and readable, with appropriate comments explaining the logic.

Areas for Improvement:

1. In "Find All Numbers Disappeared in an Array," consider adding a brief comment explaining the logic of marking indices negative and why it works.
2. For "Game of Life," the countAlive method could be made more concise by using a single loop with predefined directions, but the current implementation is clear and functional.
3. Ensure all files are properly named and avoid including system files like .DS_Store in submissions.

Strengths:

1. Both solutions are correct and efficient, with optimal time and space complexity.
2. Good use of in-place techniques to minimize space usage.
3. Clear comments explaining the approach and logic.
4. Well-structured methods and readable code.

Areas for Improvement:

1. In "FindAllNumbersDisappearedInAnArray", consider adding a brief explanation of the approach in the method's summary comment to make it more comprehensive.
2. In "GameOfLife", the countAlive method could be made more readable by using a more descriptive name, such as CountLiveNeighbors. Also, the dirs array could be declared as a constant or static field since it doesn't change.
3. Consider adding more detailed comments in the "GameOfLife" method to explain the state transitions (1→2 and 0→3) for better clarity.
