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 can't pass the random tests ... any ideas?
Hard task for me as a beginner.
Wrote quite a long spaghetti code but really enjoyed it!
The escaping characters and the null parameter made it tough for me. Nice task though!
Really nice task, harder than I initially thought. Thanks for the practise.
In Java version, the description says : "String contains only uppercase letters." (or did I get that wrong?)
but one test case contains lowercase : "assertEquals(0, Shifter.count("js"));"
Maybe you want to adjust the description text.

Would be nice to change "mean" in the description to "arithmetic mean" or "average value". The translation of "mean" to my language is ambiguous (it can be translated to "minimum" as well).
