hey look at the kata
Translate Dart

What did you find confusing about the description? I thought it was pretty easy to understand.

The hardest thing in this kata is its description. It's unclear.
Gentlemen, please, when you make your katas, be merciful. Don't make users feel confusing.

why did they change the avatar

Excellent Kata, thank you. The tests are tricky.

Nice Kata, if you go with Java then nice warm up for java Stream api...

you are mutating the input array, this is why the assertion messages are confusing. i patched the tests so that the message is computed before the function call. your code is incorrect though, you need to fix it. also note that mutating your input when you are not asked to is bad practice, and in this kata in particular it cannot work as sometimes you will need to add an element.

There is no problem in the description, your code needs to validate the input.
