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.

How do you solve this?
bottom right corner of basic test no.7:
1 1 1 0
1 x 2 1
1 2 ? ?
0 1 ? ?
1 2 2 ?
x 2 ? ?
1 2 ? ?
this is the answer:
1 1 1 0
1 x 2 1
1 2 x 1
0 1 1 1
1 2 2 2
x 2 x x
1 2 2 2
but i find it could be like this as well:
1 1 1 0
1 x 2 1
1 2 3 x
0 1 x 2
1 2 2 2
x 2 x 1
1 2 1 1
yet the kata doesn't expect '?'
Wow that's actual genius🙀🔥
Please can you explain this one? I'm struggling to follow it.
Well done😁
How does that work since list.append() is not boolean?
