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 agree Linq methods not always the best option for performance. :)
Nope :D Is is clever, but not best practice
Is it readable?
This comment is hidden because it contains spoiler information about the solution
maybe add some string interpolation or string format here?
yeah, sorry, I mean it needs to allocate new string each time and when you make char.toUpper() + new string() it needs to allocate another string cuz strings are immutable, so it allocates 2 instances of string every iteration and then gc needs to collect all of those objects. I guess stringBuilder is better in case you need more performance.
Please, can you explain? You mean it is slow, or that it will not work? Or it will do something else than requested?
total performance fail
