mergesort

void MergeSort(int A[], int n, int B[], int C[]) { if(n > 1) { Copy(A,0,floor(n/2),B,0,floor(n/2)); Copy(A,floor(n/2),n-1,C,0,floor(n/2)-1); MergeSort(B,floor(n/2),B,C); MergeSort(C,floor(n/2),B,C); Merge(A,B,0,floor(n/2),C,0,floor(n/2)-1); } }; void Copy(int A[], int startIndexA, int endIndexA, int B[], int startIndexB, int endIndexB) { while(startIndexA < endIndexA && startIndexB < endIndexB) { B[startIndexB]=A[startIndexA]; startIndexA++; startIndexB++; } }; void Merge(int A[], int B[],int leftp, int rightp, int C[], int leftq, int rightq) //Here each sub array (B and C) have both left and

This is a question from Introduction to Algorithms By Cormen. But this isn't a homework problem instead self-study. There is an array of length n . Consider a modification to merge sort in which n/k sublists each of length k are sorted using insertion sort and then merged using merging mechanism, where k is a value to be determined. The relationship between n and k isn't known. The length of array is n . k sublists of n/k means n * (n/k) equals n elements of the array. Hence k is simply a limit at which the splitting of array for use with merge-sort is stopped and instead insertion-sort is

The question is : UNBALANCED MERGE SORT is a sorting algorithm, which is a modified version of the standard MERGE SORT algorithm. The only difference is that instead of dividing the input into 2 equal parts in each stage, we divide it into two unequal parts – the first 2/5 of the input, and the other 3/5. a. Write the recurrence relation for the worst case time complexity of the UNBALANCED MERGE SORT algorithm. b. What is the worst case time complexity of the UNBALANCEDMERGESORT algorithm? Solve the recurrence relation from the previous section. So i'm thinkin the recurrence relation is : T(n)

Im trying to do a mergesort implementation to find the number of inversions. . The array seems to return the right results for a small list of numbers that are hard coded, but returns an incorrect number when I read from a file. I guess its something to do with string- integer comparison, but cant figure out what exactly the issue is, . Any insight would be helpful.Here's the (relevant) code- public class ReadFile { public static void main(String args[]){ int count=0; int n[]; int i=0; try{ n=OpenFile(); int num[] = new int[n.length]; for (i=0;i<n.length;i++){ num[i]=n[i]; // System.out

I'm currently working on an analysis project where I'm observing how different algorithms behave when implemented in Java. I got some code which implements a Mergesort algorithm from online, now I need to run this code on an array of 10,000 randomly generated integers (between 1 and 100,000) and record how many swaps and comparisons were made. I'm not exactly sure at which point in the code to increment the variables that count Swaps and Comparisons. What would the expected value be? Since best, worst, and average case for Mergesort are all nlog(n) does this mean I should expect 10,000*(log
