QuickSort Worst-Case Time Complexity The worst-case situation is when the partitioning algorithm picks the largest or smallest element as the pivot element every time. The worst-case time complexity of quicksort is O (n2) .

Which is the best sorting algorithm? If you've observed, the time complexity of Quicksort is O(n logn) in the best and average case scenarios and O(n^2) in the worst case. But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.

Insertion Sort We want to sort A in ascending order. Insertion Sort is an algorithm to do this as follows: We traverse the array and insert each element into the sorted part of the list where it belongs. This usually involves pushing down the larger elements in the sorted part.

Among the given sorting algorithms, insertion sort has the worst-case time complexity of O(n^2).

Worst case: O(n²). Since we loop through n elements n times, n being the length of the array, the time complexity of bubble sort becomes O(n²). Best case: O(n²). Even if the array is sorted, the algorithm checks each adjacent pair and hence the best-case time complexity will be the same as the worst-case.
