Which of the following is not a stable sorting algorithm? Explanation: Out of the given options quick sort is the only algorithm which is not stable. Merge sort In computer science, merge sort (also commonly spelled as mergesort) is an efficient, general-purpose, and comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the order of equal elements is the same in the input and output. › wiki › Merge_sort
Which of the following sorting algorithm is are stable?
4. Which of the following sorting algorithm is stable? Explanation: Out of the given options binary insertion sort is the only algorithm which is stable.
Which of the following sorts is not stable?
Stable and Unstable Sorting Algorithms
Several common sorting algorithms are stable by nature, such as Merge Sort, Timsort, Counting Sort, Insertion Sort, and Bubble Sort. Others such as Quicksort, Heapsort and Selection Sort are unstable.
Which of the following is not sorting algorithm?
The correct answer is (B) Quick Sort.
Why is selection sort not stable?
Selection sort works by finding the minimum element and then inserting it in its correct position by swapping with the element which is in the position of this minimum element. This is what makes it unstable.

Which of the following is not in place sorting algorithm by default? Explanation: Fast sort, heap sort, and insertion sort are in-place sorting algorithms, while merging two sorted arrays requires an additional space of O(n). We have a merge sort variant (to do in-place sorting), but it is not the default option.
Which is not a stable sorting algorithm in Python?
These sorting algorithms are usually not stable: quicksort. heapsort. selection sort.
What is stable or unstable algorithm?
A sorting algorithm is said to be stable if it maintains the relative order of numbers/records in the case of tie i.e. if you need to sort 1 1 2 3 then if you don't change the order of those first two ones then your algorithm is stable, but if you swap them then it becomes unstable, despite the overall result or ...
Which of the following sorting algorithm does not use recursion Mcq?
To make the right element as the root is heap sorting. It does not use recursion.
Is merge sort in-place?
Because it copies more than a constant number of elements at some time, we say that merge sort does not work in place. By contrast, both selection sort and insertion sort do work in place, since they never make a copy of more than a constant number of array elements at any one time.
Why radix sort is stable sort?
It is very important that radix sort use a stable sort for sorting on the digit values in each position. This is because once an element has been assigned a place according to the digit value in a less significant position, its place must not change unless sorting on one of the more significant digits requires it.
Are merge sort and quick sort stable sorts?
Merge sort is stable as two elements with equal value appear in the same order in sorted output as they were in the input unsorted array. Quick sort is unstable in this scenario. But it can be made stable using some changes in code.
Is heap sort better than merge sort?
The merge sort is slightly faster than the heap sort for larger sets, but it requires twice the memory of the heap sort because of the second array.
What is merge sort algorithm?
Merge sort is a sorting algorithm based on the Divide and conquer strategy. It works by recursively dividing the array into two equal halves, then sort them and combine them. It takes a time of (n logn) in the worst case.
Why is quicksort the best sorting algorithm?
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 sorting algorithms.
Is naive QuickSort stable?
Yes, naive quicksort is stable because the partitioning algorithm is stable since it maintains the relative ordering of equal items.
