If there was a way, it would be the new insertion sort! Theoretically you could reduce the time by using a linked list and searching to the position it needs to be inserted and inserting it. In practice however you would be better off simply using a different sort, especially if you don't want your data in a linked list.

Selection sort is better when writing is expensive. Quicksort and Mergesort are faster on large data sets.

Which algorithm is more efficient- insertion sort algorithm or merge sort algorithm?

On average merge sort is more efficient however insertion sort could potentially be faster. As a result it depends how close to reverse order the data is. If it is likely to be mostly sorted, insertion sort is faster, if not, merge sort is faster.


Who invented insertion sort?

There are no records of when insertion sort was invented because people have been sorting things using the insertion sort and selection sort algorithms since before records began; they are ancient algorithms. You cannot be credited for creating an algorithm that already exists. Shell sort, which is a refinement of insertion sort, was developed much later, in 1959 by Donald Shell. His algorithm can be credited because it takes advantage of a computer's processing abilities, whereas insertion sort and selection sort rely purely on a human's processing abilities.


Why comparisons are less in merge sort than insertion sort?

the main reason is: Merge sort is non-adoptive while insertion sort is adoptive the main reason is: Merge sort is non-adoptive while insertion sort is adoptive


What are the advantages of insertion sort?

It is less efficient on list containing more number of elements. As the number of elements increases the performance of the program would be slow. Insertion sort needs a large number of element shifts.

Who is best merge sort or insertion sort?

Merge sort is good for large data sets, while insertion sort is good for small data sets.

When would you use bubble sort?

Never. Bubble sort is often cited as an example of how not to write a sorting algorithm and is used purely as a programming exercise. It is never used in production code. Although reasonably efficient when sorting small lists, an insertion sort performs better on average. But for larger lists it has no practical uses. A merge sort is better for large lists, but if stability isn't an issue a quick sort is even better. Hybrid sorts typically use quick sort until a partition is small enough for an insertion sort to complete the job.


What is sorting .Design and develop an algorithm for insertion sorting?

Sorting algorithms arrange items in a set according to a predefined ordering relation. Algorithm : Insertion Sort Input : n, Size of the input domain a[1..n], array of n elements Output : a[1..n] sorted Method for j= 2 to n in steps of 1 do item = a[j] i = j-1 while((i>=1) and (item<a[i])) do a[i+1] = a[i] i = i-1 while end a[i+1] = item for end Algorithm ends
