It is 4⁽³⁶⁾ so your calculation is wrong. The last digit of that is 4: https://www.wolframalpha.com/input/?i=%284%5E%283+%5E6%29%29+mod+10

You're doing this instead: (4³)⁶

Found a false testcase "int[4,3,6]" in C#.
My calculation:
4 ^ 3 ^ 6 = 4 ^ 18 = 68.719.476.736
I expect 6 to be the last digit, or am i wrong ?

My Output:
SampleTest
Log
4:18
Test Failed
Expected: 4
But was: 6

iam sry for the confusion. i simply saw the failure and didnt examine it. thx for your help

I see what's wrong in your solution, added some more fixed and random tests to invalidate it. I was confused because the exception you added surely had nothing to do with your code passing by luck.

Yes, i am talking about the python version. I got my code runnable on 3rd try again. I got 2 Failures ("'98th' should equal '97th'", input is > 1000). This code shouldn't pass, but it does quite quickly.

That's weird because the control function expects "65th" for "6493" (you can test that yourself copying it) and there is not fixed test for that year, are we talking about Python version right?

Should be so. Therefore i pointed out this issue, because my solution did pass, which it shouldn't have.
I added this exception, because it showed me one test asser_equal("64th", getCentury(6493)).

The expected value for that year is 65, what your code returns is wrong. You can't expect random tests to cover all the years from 1000 to 9999, they're only 100. If by chance it would test for 6493 your code wouldn't pass.

i got this scrappy code runnable by setting an exception {if (year == 6493): return "64th"}

Sorry, but be more specific about what the issue is or it'll get closed.
