Strengths:

• The solution is efficient and correct, with optimal time and space complexity.
• The code is clean and well-commented, making it easy to understand.
• The use of in-place marking to track present numbers is a clever optimization.

Areas for Improvement:

• The variable name val could be more descriptive, such as currentNum or absVal.
• The comment at the top of the file (TC and SC) is good, but it could be expanded to briefly explain the approach.
• The solution could include a brief explanation of the logic in the comments, especially the part where negative values are used to mark presence.

Strengths:

• The solution is efficient, with optimal time and space complexity.
• The code is clean, well-commented, and easy to understand.
• The use of in-place marking to track seen numbers is a clever optimization.

Areas for Improvement:

• While the solution is correct, it would be beneficial to add a brief comment explaining the overall approach at the beginning of the method. This would help other developers quickly grasp the logic.
• The variable naming is good, but using more descriptive names like absVal instead of val could further enhance readability.
