fixed in the last version

solved

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.

ofc the point of the kata is not to be a good cryptography method, rather give a second perspective into the basic number theory and symbols. I'll fix the test cases

Thanks

I find most kyu 4 more easy than this kata.

Maybe just return false if no solution exist, but I agree, your points are fair ones

please approve.

clarification of the other comment: by 2 different operators, I meaned 2 different string versions of the same operator

This kata have several issues:

• sometimes uses << < < or >> > > with no added value, why adding to 2 different operators???
• oblies to return an array in the order the numbers appeared, limiting some types of solutions, and gives no explanation for it, it is not specified in the descripion, and same as before, it adds no value to the kata
• if the kata oblies to return all possible solutions, why if only 1 solutions exist, needs to be returned a an [] and not the same than any other case, an nested array, like: [ [] ]
• relies on depracated Test module

otherways great kata, super fun, should be kyu 4 at least... this can't be the same as splitting a url.

EDIT: I forked the kata, please approve, I speeded up the solution and make the changes aformention in the top section. Fork bellow:

This kata is kyu 2 for sure

Al final lo hiciste po!

very clean!

It takes less than 8ms to generate all permutations. why would you

This is awesome. It's taking two birds out with one bullet. I was trying something similar but didn't manage to close it out. Thanks for the beauty
