I thought it ignored only stuff like spaces and comments, that's weird because the codes are different and they are valid solutions only casually because of the current kata design. If it changed part of them could be invalidated.

I think certain small changes are ignored when grouping solutions

This aggroupment is weird... some split on ",", others on space, others use default argument.

• duplicate
