Created August 26, 2013 17:01
A simple sort result checker used to test the correctness of sorting function in a black box setting. This is taken from http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.112.3042&rep=rep1&type=pdf .
let x = [1;3;4;5;1;2;10;7];;
let y = List.sort compare x;;
let convert_pos list n =
let rec aux i r = function
| [] -> r
| e::t -> aux (i+1) (r @ [e*n+i]) t
in aux 0 [] list;;
