i can't even comprehend the maths in my head

Hahaha

This is awesome! Thank you!

Thanks, this is so helpful.

Just some awesome Math!

This is nice and clean

wow

its a lot quicker to perform a Math. function than an if.

Mindblowing, I was thinking on searching the last positive and do the sum with each first positive (yes, ignoring the negatives since they ruin the max sum) but that is very ineficient and also I had to use another function since lastIndexOf returns the last index of a especific element and I wanted a more general request

Thanks for breaking this down. My head was hurting.

Thanks! Chart really makes this solution much more clear

This solution took me one entire day plus the night to figure it out. Very very clever!

Sorry!

While your point is interesting, it goes without saying. Changes to the task are outside the task's scope.
