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.

this solution isn't correct; your test it by reducing the range (ex: 0 to 2, 0 to 3 ....)
I show your test mistakes.
You should use very small range (ex: 0 to 5, to 4 ....).
lol! I use bool declaration in this solution. After I see your solution, I realized my bool isn't needed. and when I use bool, mean I put conditions (true A and true B). When that condition meet, I still got error at test6 because test6 has trick by putting a or b as null. Then I add 2 more conditions. Now I feel pissed when I know this solution doesn't need condition lmao!
