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.
Most likely because whoever wrote this didn't realize it can be solved in O(1). Or because this kata is listed in the section "LINQ excercises" so the author tried to solve it using System.Linq library. I don't think it can be solved in O(1) using language integrated query.
Same here, that is a bit inexpected tbh.
Is the tests include thread safety issue?
Your joke really funny :D
If you guys failed on randow test, just attempt submit again.
I resubmit same code multiple times, somehow manage to passed random test.
For those who think your solution is correct make sure reorder your rank by name if two or more people have same score. Stuck on there for a while
Why use O(N) approach when it's a O(1) problem?
Why using pow on the first place I think. Bitwise operation much faster

It's clearly readable solution, but it should run on O(n^2). How come this solution marked as best practice when there is an approach that run on O(n)?
I like this approach better than one line solution but takes O(N^2). In my solution I utilize ASCII map instead of using a dictionary.
