Which sorting algorithm uses least memory?

Among the sorting algorithms that we generally study in our data structure and algorithm courses, Selection Sort makes least number of writes (it makes O(n) swaps).

Which sorting algorithm has the least number of swaps?

ANSWER: Selection sort Hence, we say that selection sort takes the minimum number of swaps.

Which of these algorithms has the fewest number of swap operations in terms of N )?

selection sort
One thing which distinguishes selection sort from other sorting algorithms is that it makes the minimum possible number of swaps, n − 1 in the worst case.

Which sorting algorithm is best for swapping?

Insertion Sort is suitable for arrays of small size. It also achieves best-case complexity of O(n) if the arrays are already sorted.

Which sorting algorithm uses the most amount of memory?

place sorting algorithms
The amount of extra memory required by a sorting algorithm is also an important consideration. In place sorting algorithms are the most memory efficient, since they require practically no additional memory. Linked list representations require an additional N words of memory for a list of pointers.

Which is the most efficient sorting algorithm?

Quicksort. 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.

Which algorithm needs maximum number of swaps?

Insertion sort – Worst Case input for maximum number of swaps will be already sorted array in ascending order. When a new element is inserted into an already sorted array of k size, it can lead to k swaps (in case it is the smallest of all) in worst case.

Which sorting algorithm needs minimum number of comparisons?

Merge-insertion sort is the sorting algorithm with the minimum possible comparisons for n items whenever n ≤ 15 or 20 ≤ n ≤ 22, and it has the fewest comparisons known for n ≤ 46.

Which sorting algorithm does the fewest comparisons in general?

Which sorting algorithm has the lowest worst case complexity?

Sorting algorithms which has the lowest worst case complexity – Algorithms – Merge sort.
