This solution uses two loops (filter and sum) instead of one for loop in the traditional one. So yes, in the terms of performance this is definitely not the best solution.

Question! does it return 0 when the array is empty or has just a 0? I guess so. It wouldn't be approve otherwise but I was not sure about it and my approach was pretty similar instead I used v -> v >= 0, maybe unnecesary after a double check 🤔

it's very conventient once you wrap your head around it and will trivialize a lot of problems

ong, i didn't know that thing existed

I did not know that Java has functional patterns / iterators. Nice!

me rn xd

Using loops hurts my brain less, I'm still trying to wrap my head around streams

just bookmarking this

you used stream because it looks cool, i used stream because i'm too lazy to type a loop solution.
we are not the same.

noice hahaha. i like this one

Clever solution, but for this particular Kata I prefer the traditional for loop.

Hi @tfuerholzer, I'd really like to get this Kata translated to Kotlin.

I forked your translation, and proposed a solution which already uses Kotlin 1.5 features.
You may have a look. Let's get this thing approved!

I'll never use Streams for small data, or simple loops like this one. This is easily a one liner with a for loop and the gain in readability is probably none.

Please use spoiler flag next time.
