QUESTION

We can determine how "out of order" an array A is by counting the number of inversions it has.

Two elements A[i] and A[j] form an inversion if A[i] > A[j] but i < j. That is, a smaller element appears after a larger element.

CHALLENGE

Given an array, count the number of inversions it has. Do this faster than O(N2) time.

   return qs ? `${url}?${stringify(qs}` : url;

history.push(routeTo('admin/view/:id', { id: 'ok'}, { anotherParam: 'value' }));

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

/*
In the node.js intro tutorial (http://nodejs.org/), they show a basic tcp 
server, but for some reason omit a client connecting to it.  I added an 
example at the bottom.

Save the following server in example.js:

var net = require('net');
