WHAT IS BEING ASKED

Developed by IBM Research. Submit source code sorting an encrypted vector of values in [0, 255].

The reference approach computes each element‘s destination by counting how many elements are smaller, using pairwise differences through an approximate sign, then applies the permutation arithmetically.

HOW IT IS EXECUTED

A challenge uses the same benchmark infrastructure as the rest of the platform. The submission supplies the challenge context; what runs is the implementation itself, against the challenge benchmark cases on its eligible runners.
