Is it suppose to create 9X9 grid? When I run it, it doesn't do anything and just wait. But if I click verification, it somehow verifies the task and give me pass (or fail). I have intentionally commented last line so that it doesn't pass the verification and allow me to attach my code. IntelliJ had no problem of running other course tasks so far. I think this issue may not be related to my actual code but something related to IntelliJ setting but I have no idea how to fix it. And how is it running without main method?
