Which sorting algorithm is faster Mcq?
Daniel Martin
Updated on June 01, 2026
Explanation: Optimised Bubble sort is one of the simplest sorting techniques and perhaps the only advantage it has over other techniques is that it can detect whether the input is already sorted. It is faster than other in case of sorted array and consumes less time to describe whether the input array is sorted or not.
Beside this, which of the following sorting algorithm is the fastest Mcq?
Explanation: Because of its highly optimised inner loop, Quick Sort is the fastest known sorting algorithm.
Beside above, which sorting algorithm is faster? Quicksort
Similarly, which algorithm is better for sorting between bubble sort and quicksort Mcq?
Explanation: It is O(log2n), therefore complexity will be logarithmic. 28.
What is the other name for a Shell sort algorithm?
Explanation: The other name for a shell sort algorithm is diminishing decrement sort as the distance between comparisons decreases as the algorithm runs until the last phase.

What is the principle of merge sort?
Merge sort is one of the most efficient sorting algorithms. It works on the principle of Divide and Conquer. Merge sort repeatedly breaks down a list into several sublists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list.What is the disadvantage of selection sort?
The main advantage of the selection sort is that it performs well on a small list. The primary disadvantage of the selection sort is its poor efficiency when dealing with a huge list of items. Similar to the bubble sort, the selection sort requires n-squared number of steps for sorting n elements.What is the best time complexity of Bubble Sort?
Difference between Selection, Bubble and Insertion Sort| Selection | Bubble |
|---|---|
| Best case time complexity is O(n2) | Best case time complexity is O(n) |
| Works better than bubble as no of swaps are significantly low | Worst efficiency as too many swaps are required in comparison to selection and insertion |
| It is in-place | It is in-place |
Which is a stable sort?
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.What is an external sorting algorithm?
External sorting is a class of sorting algorithms that can handle massive amounts of data. External sorting is required when the data being sorted do not fit into the main memory of a computing device (usually RAM) and instead they must reside in the slower external memory, usually a hard disk drive.Which algorithm is having highest space?
Space Complexity comparison of Sorting Algorithms| Algorithm | Data Structure | Worst Case Auxiliary Space Complexity |
|---|---|---|
| Quicksort | Array | O(n) |
| Mergesort | Array | O(n) |
| Heapsort | Array | O(1) |
| Bubble Sort | Array | O(1) |
What is the advantage of Bubble Sort over other?
The only significant advantage that bubble sort has over most other algorithms, even quicksort, but not insertion sort, is that the ability to detect that the list is sorted efficiently is built into the algorithm. When the list is already sorted (best-case), the complexity of bubble sort is only O(n).What is the big O of merge sort?
Merge Sort is a stable sort which means that the same element in an array maintain their original positions with respect to each other. Overall time complexity of Merge sort is O(nLogn). It is more efficient as it is in worst case also the runtime is O(nlogn) The space complexity of Merge sort is O(n).What is the best case efficiency of Bubble Sort?

What term is used to describe an O N algorithm?
O(N) O(N) describes an algorithm whose performance will grow linearly and in direct proportion to the size of the input data set.Which of the following sorting algorithms is the fastest for sorting small arrays?
8. Which of the following sorting algorithms is the fastest for sorting small arrays? Explanation: Insertion sort is faster than simple sort for sorting small arrays.What is the internal sorting algorithm?
An internal sort is any data sorting process that takes place entirely within the main memory of a computer. This is possible whenever the data to be sorted is small enough to all be held in the main memory. This issue has implications for different sort algorithms.Which is the slowest sorting technique?
