A quick look over the above algorithm suggests … WebTime Complexity The merging of all the sub-arrays into a single array will take O (N) time, while the array of size N can be divided into logN parts, hence the worst case of merge sort is O (N log N). Let's test your knowledge. Click the correct answer from the options. The worst-case scenario time complexity of the MergeSort algorithm is:

WebWorst case time complexity It is the slowest possible time taken to completely execute the algorithm and uses pessimal inputs. In the worst case analysis, we calculate upper bound on running time of an algorithm. We must know the case that causes maximum number of operations to be executed. Let us consider the same example here too. The time complexity of O(N) can occur here, But only in case when the given array is sorted, in either ascending or descending order, but if we have MaxHeap then descending one will create the best-case for the insertion of the all elements from the array and vice versa.
