Dec 22, 2017 at 19:00 comment added Will Ness @greybeard non-in-place quicksort is just a treesort so should be straightforward to handle, with logarithmic simulated "stack". as for Ackermann, the size will be substantial but it shouldn't change anything. this is not about turning a recursive process into an iterative one; just about simulating the stack on the heap.
