Like quicksort, quickselect has good average performance, but is sensitive to the pivot that is chosen. If good pivots are chosen, meaning ones that consistently decrease the search set by a given fraction, then the search set decreases in size exponentially and by induction (or summing the geometric series) one sees that performance is linear, as each step is linear and the overall time is a constant times this (depending on how quickly the search set reduces). However, if ba… WebThen the recursive call will be quickSelect(arr,0,pi-1), where low=0 and high=pi-1. ... The worst-case time complexity of this method is O(n 2).
