In their book 'Algorithms to Live By', British scientist Professor Brian Christian and science writer Tom Griffith said sock-pairers should try using an algorithm known as a radix sort.

I'm trying to figure out a nasty homework problem, but cant seem to wrap my mind around the two dimensional arrays in question.The problem is to implement a simple radix (aka Bucket/Bin/other name ...

If you take sorting socks as an example, the finished dish is a matching pair of socks. The algorithm Christian recommends here is a radix sort.
