WebMay 4, 2024 · So, for the given array, this pivot will split the array randomly, most probably in the middle. So, now the recurrence will be. T (n) = 2T (n/2) + O (n) which will be O (n * Log (n)). That's why we consider randomized quicksort better than standard quicksort, because, there is very low probability of bad splits in randomized quicksort.

WebQuicksort's best case occurs when the partitions are as evenly balanced as possible: their sizes either are equal or are within 1 of each other. The former case occurs if the subarray has an odd number of elements and the pivot is right in the middle after partitioning, and each partition has (n-1)/2 (n −1)/2 elements. WebQuestion: MODIFIED QUICKSORT Consider the modification of the deterministic quicksort algorithm described in class so that, instead of selecting the first element in an nn-element sequence as the pivot, we choose the element at index ⌊n/2⌋⌊n/2⌋, that is, an element in the middle of the sequence.
