Thanks. I'm confused with numbers

Print stuff and see which cases you miss.

Why do you ever want to return 43? You must return a digit.

It's difficult to tell without seeing your code. You can post your code here (see how) so we could check it, or you can ask for help in #cpp channel of Codewars Discord.

Thanks :) kata has been successfuly complete, perhaps not in the best way)

I can see a couple of problems with this code:

• It doesn't correctly handle 0 digits after the decimal point. The result shouldn't be muliplied by 10 in that case.
• It doesn't handle trailing spaces if there is also a decimal point.

First, copy whatever code you have to an editor.
Do a "RESET" on your solution within Codewars.
And then incorporate back your code into the scaffold.
I hope this fixes it.

I use only duplicateCount(const std::string& in), and pass simple test. But when i click "Attempt"? i got this error

STDERR
-isystem /runner/frameworks/cpp error: redefinition of 'duplicateCount'
size_t duplicateCount(const std::string& in)
^
note: previous definition is here
size_t duplicateCount(const std::string& in) // helper for tests

Why?
Thank you.
