Frage
I am wondering why QuickSelect is supposed to be such a good performing algorithm for finding an arbitrary element out of an n-sized, unsorted set. I mean, when you go through all elements one by one, until you find the desired one it took O(n) comparisions - That's as much the quickselect's best case and much easier.
Am I missing something essential about this? Is there a case the QiuckSelect is performing better, than linear search?
