I don't think it's possible to modify the Haskell translation to use Ints instead of Floats without invalidating most of the existing solutions. As a compromise, I've forked the translation so that the random test cases generate integer valued Floats to satisfy the description.

Please add fixed/sample tests with leading/trainling white space.

There's an issue with Random Tests, as it tests against lowercase && uppercase characters. While description clearly states:

Input/Output

[input] string str

A string consists of lowercase latin letters, digits and symbols.

However, it always brings something like:

With s = "]KK"
Expected
:
to equal
: KK

Fixed in latest fork above

I've made a fork here that adds the signature to the solution setup code. Making the solver guess what the type signature should be is completely out of the scope of this kata.

Approved

Fixed Julia, checked all languages as well, closing

Haskell fork that adjusts random test cases to filter out inputs that contain an operation that wraps the memory value

Haskell fork with random tests.

approved

character range for Julia is a-z, so it does contain invalid characters

Fixed for Java. Other affected languages are:

• C#,
• Groovy
• Not sure about Julia,
• Rust generates only 'a' fixed
• TypeScript
