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.
I saw something weird and I didn't really know where to report it, hope this is okay.
In C, I noticed a test case that made no sense:
Unless I'm missing something, the expected result should not contain 'A' or '?'.
Also, every other test was commented, so I came to raise an issue. However, I wanted to double check before posting, and now all the tests are okay and uncommented. Furthermore, seems like one of the tests in the "Test cases" section is missing when you try to solve the kata (the last one).
Is this normal? Was someone messing up with this kata?
