Why are you sorting them? You're not supposed to do that.

Who can explain me this error:

expected [ 'HK', 'KL', 'MU', 'VY', 'ab', 'eg', 'jn', 'no', 'pq', 'tv' ] to deeply equal [ 'Mq', 'Kb', 'aj', 'pV', 'nv', 'Kg', 'Yn', 'Uo', 'He', 'Lt' ]

My function return [ 'HK', 'KL', 'MU', 'VY', 'ab', 'eg', 'jn', 'no', 'pq', 'tv' ] and I think it's right because it's normal sort by alphabet.

I don't understand how we can get [ 'Mq', 'Kb', 'aj', 'pV', 'nv', 'Kg', 'Yn', 'Uo', 'He', 'Lt' ] when we sort by alphabet

I don't understand why I've got "Wrong output for '123': expected true to equal false"?
In instructions: must be 4 or 6 integers.
Here we have 3 integers. For sure in VS Code I've got False and it's right, but War Code expects True.
How???? 4 or 6 integers needed else it should be False, but when there are 3 integers it says: "it should be True". How???

Fantastic. How did you reach it?

You can't. But don't worry fot that.

I'm sorry about that. Thank you for your assistance.
How can I delete it?

Please use a spoiler flag when you post code, so that users who didn´t solve the kata cannot see it; I put the flag for you this time. Also use markdown tags to format your code or it's not usable.
