/*
Wikipedia says: Comb sort improves on bubble sort.

The basic idea is to eliminate turtles, or small values
near the end of the list, since in a bubble sort these slow the sorting
down tremendously. Rabbits, large values around the beginning of the list,
do not pose a problem in bubble sort.

In bubble sort, when any two elements are compared, they always have a
gap (distance from each other) of 1. The basic idea of comb sort is
that the gap can be much more than 1. The inner loop of bubble sort,
which does the actual swap, is modified such that gap between swapped
elements goes down (for each iteration of outer loop) in steps of
a "shrink factor" k: [ n/k, n/k2, n/k3, ..., 1 ].
