Update reverse.java #61
Conversation
This reverses 2D arrays, you can further use it solving matrices problems
Reviewer's Guide by SourceryThe PR adds a resource cleanup improvement to a Java program that handles 2D array reversal. The main change is the addition of a Scanner close operation to prevent resource leaks. No diagrams generated as the changes look simple and do not need a visual representation. File-Level Changes

Hey @ashu273k - I've reviewed your changes - here's some feedback:
Overall Comments:
- Please follow Java naming conventions - method names should start with lowercase (e.g. 'reverse' instead of 'Reverse')
- Add JavaDoc documentation to explain what kind of reversal this method performs and how it can be used for matrix problems
Here's what I looked at during the review
- 🟡 General issues: 2 issues found

suggestion (performance): Consider implementing the array reversal in-place to improve performance and reduce memory usage
Instead of creating a new array, you can swap elements directly in the original array, which would be more efficient for large inputs.

suggestion: Consider using try-with-resources for better Scanner resource management
This ensures the Scanner is closed even if an exception occurs during execution.
try (Scanner in = new Scanner(System.in)) {
// rest of the existing code
}
