I think there is something wrong in js test.
e.g. Testing: [0, 1, 0, 1] should be 5,however in test it says should be 10.

I'm done [0,56,12,66,99] , but it's timeout

thinking a lot in it. I think it should be use recursive , however timeout T^T

It's so difficult for me to throw an error..

maybe you include zero

I don't know how to replace "/"

I don’t know how to process with with horizon.

I don't understand why I am timeout

the same problem

if it's possible, i wannan see the node function, becuase i can't find out why everytime i value the node and then the rest are all the value i set at first.

in fact ,this kata is very good for me to understand the list, however at first I don't know what's the meaning of the head and the tail function.
After I try a lot of times, I finally got it.
