That's the problem I have now, haha. I only consider real life years...
I have to modify my function...

Wait I think I figured it out...

Another example of why I'm confused:

test case where input = 451054599
correct result is 21
my result 112

451054599 % 13 = 8
21 % 13 = 8
112 % 13 = 8

I just meant it's funny that if I input my incorrect result as input, the new result is the correct answer.

My code is working on everything besides 33 of the random tests. I logged n to see what the input is and it doesn't seem any different than the other test inputs other than it being a different number. Can't figure out what is causing the majority of inputs to work, but not for a few.

113 is what your function returned instead of 22, to see what the input is, print it, it'll appear above the test result, read this: https://docs.codewars.com/training/troubleshooting/

Anyone know the difference here between the random tests and basic tests?

I'm passing all basic tests and 168 / 201 random tests.

failed random test example: expected 113 to equal 22.

Locally if I input 113 as n the result is 22.

What am I doing wrong?

Very bad description for this Kata!

Sorry, I already delete or edit the comment, I'm new to this

Going by the instructions given, the result is incorrect.

I'm sure that is part of the reason this is only rated at 85%.

I've changed difference for distance to make it crystal clear.

Difference means: the result of subtracting one number from another. How much one number differs from another. From the title "Compare with Margin", the difference is going to be a positive number since you are comparing the the difference between the 2 numbers given and the margin. Say on the number line you have a point at -5 and another point at 6 and you are trying to see if the margin between the 2 numbers is less than 12. You would not say because -5 -6 = -11 and -11 is less than 12, you would get the absolute value of -5 - 6 and compare the two. It doesn't need to be explicitly written in the directions.

The instructions don't say either a-b or b-a, they say very clearly a-b. They don't mention the difference having to be a positive number.

in my example:

a-b = (-1272 - 7169) = -8441. Does it not?
-8441 is less than the given margin (1339). Is it not?

According to the instructions given, these params would return 0.

Do you know what margin means? When you measure something, and it's not an exact measure, the number is noted as X ± Y where Y is the margin or tolerance. With a difference of 8411 (or -8411) and a margin of 1339, does that sound "close" to you? Close -> distance.
