The quicksort algorithm works by partitioning a section of the unsorted array into a left part and a right part, based on a chosen element within the array called the pivot. What is the runtime complexity of the partition() method used by quicksort()? void quicksort(int[] numbers, int startIndex, int endIndex) // Only attempt to sort the array segment if there are // at least 2 elements if (endIndex e startIndex) return; // Partition the array segment int high = partition(numbers, startIndex, endIndex); // Recursively sort the left segment quicksort(numbers, startIndex, high); // Recursively sort the right segment quicksort(numbers, high +1, endIndex); O(N2) O(N) O(logN) O(NlogN)
