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.
this is not performant. it goes over list multiple times
Copy that. Thank you!
not usually best practice, in real life strive for readibility while being able to make your code shorter
I keep forgetting I don't need to make new variables for everything and it can all usually fit inside a return statement. Unsure at my level if that is the best practice, but the fewer lines of code is what I'm currently striving for as I learn.
This is a smart one.
No but tests guarantee that there is ever only two different numbers, one of them unique.
It would indeed.
That's what I've done.
Guys will that work if there is two different uniq numbers?
same hahahaha
How's that going to return [0] if arr is blank though?
wow, smart one
but if arr has three uniq numbers, Could your function run? I think it not real nice
Because your post is visible in the homepage if you don't do it for people who still hasn't solved the kata and you posted a solution in your post. That's why.
why?
