The error message in C++ hides the spaces (I don't know why but it does), you can check it returning return "HEY JUDE "; against the sample test. It'll fail and you won't see why.

You mean I have else spaces than it supposed to be?

Use question label next time, suggestion label is for your suggestions on how to improve the kata test/description/etc.
I would look for trailing/leading spaces, when copied/pasted to discussion and not using proper markdown they're lost in the post.

I passed all tests except this:
Expected: equal to SOS! THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.
Actual: SOS! THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.

It seems I am missing "equal to" how can this be different from the previous tests? Any suggestions?
