Link to the challenge:

Results are displayed, but there are differences in the arrangement. For example spacing between problems is different than in specification. For tests to pass, everything in the output needs to be the way it is expected, and even one space more (or less) in certain place will make test fail.

Thanks, there was space at the end of line, i fixed it.
