I think it might have been clearer if the description showed how an IP can have 3 failures "in a row", with other IPs in between. Perhaps changing the example input to

logs = [
    "192.168.1.1 LOGIN_FAIL user=admin",
    "192.168.1.1 LOGIN_FAIL user=admin",
    "10.0.0.5 LOGIN_FAIL user=test",
    "10.0.0.5 LOGIN_SUCCESS user=test"
    "192.168.1.1 LOGIN_FAIL user=root",

]

I initially understood the problem to mean literally in a row, but then I thought that didn't make sense for the narrative framing.

Oh, thanks a lot!

^ (caret) ... allows changes that don't modify the left-most non-zero digit

The left-most non-zero digit is the 3, so you arent allowed to change it to match the 4.

Also, please don't use the Issue tag for questions. Please use the Question tag for questions

Why test.assert_equals(satisfies("0.0.4", "^0.0.3"), False) ?

The outPut Should be alphabetically sorted ☠️

From the description:

Return a list of suspicious IPs, sorted alphabetically.

In Python, the sample tests (and presumably the actual tests) require that the output be sorted. However, this is not mentioned in the description.

I would suggest adjusting the description to specify the output must be sorted.

Approved by someone

Fixed in this JS fork, if anyone wants to review/approve.

The reason you have such confusing looking logs is because you are mutating the input. The real issue is that the random tests on JS are vulnerable to input mutation (see this solution).

(The user attempted JavaScript)

It seems to think that if the IP is the same but the user is different it shouldn't flag the IP. Is that intentional? This data expected an empty array [
'19.249.169.21 LOGIN_SUCCESS user=guest',
'19.249.169.21 LOGIN_FAIL user=guest',
'19.249.169.21 LOGIN_FAIL user=user',

good kata!
Looked easy, turned out to be tricky... (for me)

Great kata, easy to learn with.

Omg and I'm not even supposed to be the bot, you guys can't be serious...
