How many comparisons in merge sort mcq

WebThe important part of the merge sort is the MERGE function. This function performs the merging of two sorted sub-arrays that are A [beg…mid] and A [mid+1…end], to build one sorted array A [beg…end]. So, the inputs of the MERGE function are A [], beg, mid, and end. The implementation of the MERGE function is given as follows -. WebIn the worst case, merge sort uses approximately 39% fewer comparisons than quicksort does in its average case, and in terms of moves, merge sort's worst case complexity is …

WebDec 4, 2024 · The number of comparisons: This is the number of times the algorithm compares elements to sort the input. Using Big-O notation, the sorting algorithm examples listed above require at least O (nlogn) comparisons in the best case, and O (n^2) comparisons in the worst case for most of the outputs. WebThe merge () function typically gets 4 parameters: the complete array and the starting, middle, and ending index of the subarray. The start, middle, and end index are used to create 2 subarrays, the first ranging from start to middle and second ranging from middle to end. At this point, each subarray is in the correct order.

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 ... WebMay 4, 2024 · Approach: The problem can be solved using Divide and Conquer Algorithm ( Merge Sort ). Follow the steps below to solve the problem: Split the array into two halves and recursively traverse both the halves. Sort each half and calculate the number of swaps required. Finally, print the total number of swaps required.
