Approved

You should use fold instead of reduce. Because if the array is empty then reduce method will give error.

This is very clean

Too late to introduce such changes due to amount of language and solutions submitted as of now!

Rejected as it will invalidate all existing solutions (maybe use backward compatability for consideration in approval)

Probably if you are aiming to use java streams, you should have a method that checks it. I see some solutions using the for loop

this solution made me scroll so much xDD

Thanks to god you don't have to take in count special characters or special letters like "ñ" or "ç" 😂

Dart translation edited (better naming and String type)

Dart Translation Fork

the purpose of this use was to beautify the appearance of the code

of course using the array was wrong :'(

I didnt see now i am trying to solve the duplicated

Why do you publish a translation to a kata retired for being duplicate?

Why did you create an array to make just a sum?
