No output when executing code

Feedback & Bugs
#1

Hi All,

I’m having problems executing code where no output is generated. No output at all. No compiler errors, no error or output logs. All three output options are checked. I’ve tried running the code in Scala and Java with the same result.

Also I’ve tried this in Chrome 64 and Firefox 57.

Anyone have any ideas.

Any puzzle specifically or it happens for all?
