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.
Nice idea with using array instrad of dictionary. But what the point to use 2^16 size instead of 26?
In JS you're right
Rather 7 (in Ruby e.g.) Creating an issue.
Yes.

I was gonna say the same thing, but the tests are not rigorous enough so it's really the creator's fault.
In the C# version of this the tests are all using the same reference to the array so if your function modifies the array inline it will not behave as intended.
edit: To people saying this is intended, what if you write code which abuses this fact? It's probably possible to pass all tests with enough trial and error.
this is a case where you can purposefully cause side effects upon the test data between tests. not good. sloppily written tests.
