Empty line ?
Changes ?
Output ?

In the description, it says:

If the final result is longer than 140 characters, it must return false.

If the input or the result is an empty string it must return false.

While implementing my solution in Scala, I initially returned "false" as a string for this case. However, the tests were expecting an empty string instead. I suggest updating the description to specify that false should be represented as an empty string in the output.

python translation

Ruby: function name should be snake_case

There should be tests of single-character strings like #, A and a to invalidate certain solutions

C# translation ready! Please review and approve.

I guess tests should also check fo boundary values:

• an input of 1 non-whitespace letter
• an input with 139 non-whitespace letters
• an input with 140 non-whitespace letters

I am returning false i str is empty

  if (!str || str.trim() === "") return false;

then why my code further execcute it should return false. however it's working fine in console not here

Maybe it is necessary to add the condition of having only one "#" in the entire output str (at the beginning of the hashtag).
Because in my tests I've got resal like this - "#TheABC#quickBro"

what does this error mean:
src/Solution.cs(5,24): error CS0161: 'Kata.NumberToString(int)': not all code paths return a value
im using C#

I created a Swift translation of this kata, any chance for approval?
