Changed all cases of test.assert_equals to test.expect, because i genuinely didnt know how to get rid of that false should equal true at the end

As far "while" loops don't work, so i run the "while" loop in other code to print the tests.

There're no specific reason of number of tests (666).

in the description of Kata i sayd, you have class DateParser, and this class have list of function. You need create DateParse Function to optimize this class(

in this Kata you need optimize class, but you also can make you own function without DateParser class function's.

sanks for your example, now work correct i think

okay, i go fix it

Thank you, okay i fix all?

okay, None is the better solution, sanks

sory, i go fix it

and i think -50 seconds isn't correct. If we fantasy about this => okay, but in real this is uncorrect value, i think user can take a exception or False, but stopped at -1.

negative values not correct, i think -1 very nice solution. This kata for new members like 7-8 rang

okey, i add random test's

why not?

You're right about all of this; I made this because I was bored in class and didn't really stop to think about anything. Thanks.

It turns out that this problem cannot be solved in c#?

fixed the test suite.

I can make it work with BigIn, but as I pointed out, the point of the kata its not to be a good encription method. So if posible I'll just keep it as it is and keep testcase string short.

I think this Kata has historical reasons for it to exist. As you mention: "since the middle ages where Arabic scholars such as Al-Qalqashandi used letters and their assigned numerical values, systems such as the one described here have been used to encrypt messages". https://arxiv.org/pdf/2306.02378

Maybe a little mention to history like that could be added to the description.
