• H-Index.java: Your solution is correct and well-implemented, but the sorting step makes it less efficient than the reference solution. Consider using the bucket sort approach for a linear time solution.
• RotateArray.java: Excellent implementation. The three-reverse method is a great choice for this problem.
• TrapRainWater.java: Well done! The stack-based approach is efficient and correctly implemented.

Overall, your solutions are correct and well-structured. The main area for improvement is in the H-Index problem, where a more efficient approach exists. Keep up the good work!
