About Sort detective

Back in our secondary school days, chemistry students were often given an unknown compound and asked to figure out what it was via qualitative analysis. For this assignment, your job is to take several mystery algorithms and figure out what they are by analyzing their computational properties in much the same way.

We'd like to give a warm thanks to Dr. David Levine, who created this assignment "25 years ago on a NeXT computer using Objective-C," for allowing us to take his concept and put it up the web!
