How many comparisons in merge sort mcq
WebNow we have to figure out the running time of two recursive calls on n/2 n/2 elements. Each of these two recursive calls takes twice of the running time of mergeSort on an (n/4) (n/4) -element subarray (because we have to halve n/2 n/2) plus cn/2 cn/2 to merge. We have two subproblems of size n/2 n/2, and each takes cn/2 cn/2 time to merge, and ... WebDivide and conquer-based sorting algorithm Merge sort An example of merge sort. First, divide the list into the smallest unit (1 element), then compare each element with the adjacent list to sort and merge the two adjacent lists. Finally, all the elements are sorted and merged.

Web62. Under what case of Master’s theorem will the recurrence relation of merge sort fall? a) 1 b) 2 c) 3 d) It cannot be solved using master’s theorem Answer: b Explanation: The recurrence relation of merge sort is given by T(n) = 2T(n/2) + O(n). So we can observe that c = Logba so it will fall under case 2 of master’s theorem. 63.
