if type(st) != str: 
    return -1

This code should not be necessary given we are told in the problem statement that the input is a string.

python new test framework is required. updated in this fork

• No random tests in PHP

• Actual and expected are swapped

Description:

Given a string of characters...

But in JS, the input could be numbers or arrays. Either revise the description or remove non-string inputs from the tests.

Re-raised as an issue.

You can see the input.

Me neither, but it's actually mentioned in the description:

Not all strings will contain digits. In this case and the case for any non-strings, return -1.

Although it's incosistent with the instruction:

Given a string of characters,

JS: Node v12 should be used along with its appropiate assertion tools (Mocha + Chai).
Refer to this and this

just echo gettype().
If it ain't a string:

In this case and the case for any non-strings, return -1.

Kata description isn't clear. I wasn't expecting an array as an input.

Read this and check Madjosz's post below.

No, you forgot the 0 at the end.

Seems my code is returning right decision and issue on your end
