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 -. WebMar 21, 2024 · Here are the steps to sort the given items in ascending order using Bubble Sort: Start with the first two elements, compare them, and swap if necessary. Move to the next pair of elements, compare them, and swap if necessary. Repeat step 2 for all pairs of adjacent elements until the end of the list is reached.

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.
