Ruby 3.0 should be enabled.

Pretty sure this is a duplicate.

Again, unpublish temporarly your kata before it gets more and more downvotes and republish after update.

Hi,

Your kata is lacking several things or has problems:

• function name shouldn't be dir because it's a function in python (dir(list))
• maybe an argument name a bit more explicit...? (not really a problem)
• the return type as a list is really not a good idea because the order is important. You should either ask for a dictionary or specify the order in which the directions should be appended to the list
• what about several "residual" directions? (see above)
• not enough tests
• need random tests

cheers
