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.

thank you.
so the formula would be 4 * x + 5 * y = z
And we are looking for the biggist z out there that does not match the equation for any x and y values of positive int, x and y do not need to be the same. It now makes sence.
I want to try it but first, I needed to understand what is the task. (at least I am not the only one with the same problem based on the coments :D)
I looked at the description and just dont get it. I tried to base the code based on test, but it works just for the test. I have been trying to make sence from atempt numbers and description here, but still do not understand what is the kata supposed to do.
could you please explain on other examples, how did you get to the result (matematically) to understand what is code supposed to do?:
(4,5) - why is it 11?
(15,12) - why is it -1?
(20,9) - why is it 151?
(15,11) - why is it 139?
