Second and third sample tests seem to be wrong :

• [(-2, 5), (4, -1), (4, 11), (10, 5)]

  For n = 10: [4, (4, 11)] should equal [4, (4, -1)]

• [(260, 120), (264, 92), (264, 148), (280, 60), (280, 180), (300, 40), (300, 200), (332, 24), (332, 216), (360, 20), (360, 220), (388, 24), (388, 216), (420, 40), (420, 200), (440, 60), (440, 180), (456, 92), (456, 148), (460, 120)]

  For n = 100: [20, (420, 40)] should equal [20, (420, 200)]

• There are many ways to sort an array, you have to be explicit.

• Use katex for math formulas :

  (x – h)^2 + (y – k)^2 = r^2
  

• Description has be rewritten to correspond to actual quality standards.

• In light mode, your example is hard to see.

This one is crazily cool and rewarding. It should be translated to Python by a someone.

Even if the two entities of dictionary and alphabet are arbitrarily defined as follows:

let dictionary = {};
let alphabet = [];

The error feedback states:

expected NaN to equal 4359030
expected '' to equal 'SUPERMAN'

...although the expected functions temselves are strictly returning number and string values respectively, as such:

function encript(s) {
  return 4359030;
}

function decript(n) {
  return "HELLO";
}

ReferenceError: dictionary is not defined
ReferenceError: alphabet is not defined

Nowhere in the description does it tell the user to define these.

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

I am going to unpublish the kata because it is currnetly broken. The tests call functions which are not defined, and setup is not great either: the task is very impractical if it uses Number instead of BigInt. Additionally, we should really get rid of the mindset of calling juggling letters around as "encryption". It's not middle ages anymore.

ReferenceError: MYSUPERENCRIPT is not defined

encrypt, decrypt

f(n) =  \begin{cases} \frac{n}{2} \quad &\text{if }& n \equiv 0 \pmod{2}\\ 3n + 1 \quad &\text{if }& n \equiv 1 \pmod{2} \end{cases} 

The other kata is now available

I tried to reduce my code for days, not understanding why my formula was wrong!

Fixed

In the sample tests tester("11000", "01111", 4, 1):

Remove components 1 and 2, price of 1, quality of 4

Isn't it :

Remove component 1, price of 1, quality of 4

To prevent bad understanding, maybe add in the description that indices are 1-based in your sample tests.

Either could have worked. Approved with 2D array.
