ordered - suppose to have unique values

for this code:
Metrics
There is only one function in this file.

It takes one argument.

This function contains only one statement.

Cyclomatic complexity number for this function is 3.

https://jshint.com/

Metrics
There are 2 functions in this file.

Function with the largest signature take 2 arguments, while the median is 1.5.

Largest function has 1 statements in it, while the median is 0.5.

The most complex function has a cyclomatic complexity value of 2 while the median is 1.5.

I took from https://jshint.com/

in my opinion complexity 2 is quite good;

in case or more data like this
[3, 6, -8, -2, 4, 5, -1, 8, 1] => I have 2 pairs [-8,8] and [-1, 1]; what will be result in my example?
I am trying to see the big picture.

hey Remo,
I think I get better understanting.
What will happen in case of
[3, 6, -8, -2, 4, 5, -1, 8, 1] what will be the return?

hello,
I just improved the solution. please have a look;

I found a bit confuse :

in every math formula or in Matlab the symbol ^ is means "exponential"
but in Python or Javascript symbol ^ is means XOR , better to write a note/legend to explain is exponential : symbol "**"
