Your code looks fine, but the challenge validator seems to be imposing some requirements that aren't part of the language syntax rules.

In particular:

  • it seems to need a space after the comma in the type specification :point_right: Func<int, int>
  • it does not like the space after the argument name :point_right: (int number)

You might want to report these things as bugs to the Support staff.
