fixed some time ago

EDIT: nevermind

thanks!

Awesome!

The method * of the Array class has two uses:

When its argument is a string (s), its equivalent to self.join(s) (s will separate the values of self)

When it's an integer (n), it returns the concatenation of the array self n times.

Thanks for the feedback, I've fixed the issue.

Forgot to mark as solved :-)

Reversed now.

Obviously not, and test specifically tests that it isn't

Test.assert_equals false, "1\n0".digit?

because naive implementation might accidentally match that.

Nice kata

One problem though, the tests are backwards expected, actual instead of actual, expected making the error reports confusing.

"1\n0" is considered to be a digit?
