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.
Kata only provides a fixed set of test cases, which is easy to hard-code.
According to the Test I can solve test for Size 10 in ~500ms. But then I always get a time out for cases with size = 11.
I also run tests on my machine and can run all test including 11 in less than 4 seconds. Still these time outs appear.
I already try for days with crazy optimizations to make the code faster and start to wonder if its a test suite issue.
Right now I feelt his way harder than the 1 Kyu 7by7.
Please Check it it is still solveable.
