You can't really take code out of a function, remove one of the lines, and expected it to still work.

Is this a human? All your kumites are just the default python/javascript tests copied into the code section.

import codewars_test as test

TODO Write tests

import solution # or from solution import example

test.assert_equals(actual, expected, [optional] message)

@test.describe("Example")
def test_group():
@test.it("test case")
def test_case():
test.assert_equals(1 + 1, 2)

return f"Hello {n}, you are very cool!"

// Since Node 10, we're using Mocha.
// You can use chai for assertions.
const chai = require("chai");
const assert = chai.assert;
// Uncomment the following line to disable truncating failure messages for deep equals, do:
// chai.config.truncateThreshold = 0;
// Since Node 12, we no longer include assertions from our deprecated custom test framework by default.
// Uncomment the following to use the old assertions:
// const Test = require("@codewars/test-compat");

describe("Solution", function() {
it("should test for something", function() {
// Test.assertEquals(1 + 1, 2);
// assert.strictEqual(1 + 1, 2);
});
});

Rust translation uses two-space indentation while the standard for the language (rustfmt and the codewars tab size) is four.

I mean resources that have typical examples that can help in understanding programming concepts

This kind of "mistake" is exactly something what Mel the Real Programmer would do when creating software for Bundesamt für Organisation in the early computing era.

It's no coincidence. jcsahnwaldt was working for the Bundesamt für Organisation back in 1964 and purposely made this "mistake" all in preparation for this kata which he had already planned.

According to footnote 6, the Swiss Bundesamt für Organisation made a mistake in 1964. I have no doubt footnote 6 is telling the truth.
