Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
JS here. Why would the only test that's failing be the one with a super long array as param?
I didn't understand why I should calculate the mean - the value. For me it would make more sense to calculate the value - mean, because if the value is 12 and the mean is 10 I would get 2 more. The way it's asked for here gives -2, when in fact, I collected 2 contacts more. What didn't I understand correctly? There is no way everyone did this wrong, without questioning.
It's the way noobs do it lol. Just like me haha :P
The description wasn't sufficient imo.
I did not understand, that I needed to set a default value, to pass the test cases.
I'm either 1 too high with half the test cases in one "solution" or 1 too low in half the cases in another, are the test cases alright??
Why is my code not working every time?
same here
Well I solved that kata, but my while loop was so inefficient, that I got an execution time out for some tests and I could only pass the basic tests.
