Even though quick-sort has a worst case run time of Θ(n2), quicksort is considered the best sorting because it is VERY efficient on the average: its expected running time is Θ(nlogn) where the constants are VERY SMALL compared to other sortingalgorithms.

Is bucket sort stable? Bucket sort is stable, if the underlying sort is also stable, as equal keys are inserted in order to-each bucket. Counting sort works by determining how many integers are behind each integer in the input array A.

How does Bucket sort work? Bucket sort, or bin sort, is a sorting algorithm that works by distributing the elements of an array into a number of buckets. Each bucket is then sorted individually, either using a different sorting algorithm, or by recursively applying the bucket sorting algorithm. Set up anarray of initially empty "buckets".

Is merge sort in place? Unlike some (efficient) implementations of quicksort, merge sort is a stable sort. Merge sort's most common implementation does not sort in place; therefore, the memory size of the input must be allocated for the sorted output to be stored in (see below for versions that need only n/2 extraspaces).

Why is quicksort better than mergesort? Why quicksort is better than mergesort Quick sort is an in-place sorting algorithm. In-place sorting means no additional storage space is needed to perform sorting. Merge sort requires a temporary array to merge the sorted arrays and hence it is not in-place giving Quick sort the advantage of_space.
