Old Implementation
follows the chain of indices each iteration until a new index is hit, effectivly doing the same thing multiple times.
performs 2x more data moves than neccessary
New Implementation
immediatly moves the data into place following the indices chain, by using a temp variable
then skips indices it has allready visited by swapping their sign
the indices array is unchanged at the end
Benchmark
