Nice!

Length of sequence times average of sequence equals sum of sequence.

I can't seem to see the images in the description...

Excuse me, could you explain the same stuff you wrote, but for dummies who are not into math?

This one has me a little confused. How do we pass in the val parameter for this one?

nice!

My favorite one so far! Looks pretty neat.

Are there any time- & spacecomplexity Kata-Stats to checkout ?

нифига у меня 1 строка а у тебя

It looks so good but why does it work?

you're not supposed to solve this with a recusive solution, yeah.

Is it possible to pass this with Javascript?
I wrote a recursive solution that passes all the random tests without timing out, but when I hit the performance tests I run out of stack space.
Doesn't that mean that the data is so large that there isn't enough space to finish it?
I can't think of any way to reduce the number of calls...

You can use jsbench.me

Same for me.
I could have saved a lot of time if I had understood better your sentence : 'I assumed all input is ordered'.
I had to print the first and last edges of the perfomance test to get it.
Thanks for that

Yeah, was probably just being inept, as per usual :)
