title: Can someone clarify the difference between Quicksort and Randomized Quicksort?
body: <p>How is it different if I select a randomized pivot versus just selecting the first pivot in an unordered set/list?</p>
  
  <p>If the set is unordered, isnt selecting the first value in the set, random in itself? So essentially, I am trying to understand how/if randomizing promises a better worst case runtime.</p>
