FAQ
Which Java and C++ versions do you support?
Java 8 through Java 21, and modern C++ (C++11/14/17/20). Specify your version and I'll ensure full compatibility.
Can you fix build, compiler, and linker errors?

Detailed feedback on logic correctness, time/space complexity, architecture quality, security risks, and refactoring recommendations with code examples.
Do you handle data structures and algorithms?
Yes, including arrays, linked lists, trees, graphs, sorting/searching, dynamic programming, recursion, and complexity analysis.
Can you work with academic or existing client projects?
Yes, as long as code and requirements are clearly shared. I adapt to existing coding standards and constraints.
Do you provide explanations for non-technical users?
Yes. I can simplify technical terms and provide walkthrough notes for easier understanding of changes.
Can you help with test cases and edge cases?
Yes. I can review test coverage, identify missing scenarios, and suggest edge case handling improvements.
