same

Hi, thank you for sharing your work around. But in this case when I print the original incoming string, I can see that it does not contain '\t' at all, yet it is expected in the output string. I am not sure why?

I got the same and "solved" it by including \t as an acceptable character. It's a bit weird.

One of the tests expects special characters to be retained, such as ~ / \ and others. Please fix the task, or remove this test?

Are we expected to insert '\t' in result string when incoming string does not have it?
My solution is failing the following input:
st = ' S]r(2 (y%nF=<

My result is:
result = Sr2ynF
I get the following error:
' Sr2ynF' should equal ' Sr2\tynF'

Thanks

Prolog translation

Fixed in this fork

i didn't know that range function return a list . nice

nice solution

Both list comprehension and RE is O(n) in this case.

Clever but difficult to read

PHP:

• random tests do not test for non-string inputs

JS:

• mocha + chai should be enabled

• Random tests do not test for non-string inputs
