What is the space complexity of merge?

The space complexity of Merge sort is O(n). This means that this algorithm takes a lot of space and may slower down operations for the last data sets .

What is the complexity of merge algorithm?

The time complexity of MergeSort is O(n*Log n) in all the 3 cases (worst, average and best) as the mergesort always divides the array into two halves and takes linear time to merge two halves.

Why is merge sort space complexity N?

Closed 1 year ago. At first look, it makes sense that merge sort has space complexity of O(n) because to sort the unsorted array I’m splitting and creating subarrays but the sum of sizes of all the subarray will be n.

What is the address space complexity of merge sort?

It takes O(N) space as we divide the array and store it into them where the total space consumed in making all the array and merging back into one array is the total number of elements present in it.

What is the space complexity of merge sorting an array?

MergeSort time Complexity is O(nlgn) which is a fundamental knowledge. Merge Sort space complexity will always be O(n) including with arrays. If you draw the space tree out, it will seem as though the space complexity is O(nlgn).

What is the space complexity of merge sorting a linked list?

The mergesort algorithm is recursive, so it requires O(log n) stack space, for both the array and linked list cases. But the array case also allocates an additional O(n) space, which dominates the O(log n) space required for the stack. So the array version is O(n), and the linked list version is O(log n).

What is the auxiliary space complexity of merge sort Mcq?

What is the auxiliary space complexity of merge sort? Explanation: An additional space of O(n) is required in order to merge two sorted arrays. Thus merge sort is not an in place sorting algorithm.

How much space does merge sort use?

Space complexity Method merge requires an extra array of size e+1-h. Here, e is the average of h and k, so mergeSort requires space O((k+1-h)/2) while the call on merge is being executed. That’s actually O(k+1-h). The recursive calls also require space, but half as much, and not at the same time.

What is the space complexity of merge sorting and array?

What is space complexity of merge sorting a linked list vs merge sorting an array?

What are the average time complexity and auxiliary space complexity of merge sort?

This is because it splits the array into two halves and applies the merge sort algorithm to each half separately before merging the two sorted halves. 13. What is the average case time complexity of merge sort? Explanation: T(n) = 2T(n/2) + n is the recurrence relation for merge sort.

What is the average case complexity of merge sort?

O(n log n)
Merge Sort is an efficient, stable sorting algorithm with an average, best-case, and worst-case time complexity of O(n log n). Merge Sort has an additional space complexity of O(n) in its standard implementation.
