merge sorting, Data Structure & Algorithms
ESO207: Programming Assignment 1
Due on 6 Sept, 2015. To be submitted online.
Problem In this assignment you are required to implement kway Merge Sort algorithm. In this version partition the input sequence of integers into k almost equal (may di?er by at most 1) subsequences, recursively sort, and then merge the k sequences. Input: A positive integer n, a sequence of integers (a1,a2,...,an), and a positive integer k = 2. Goal: Design a program KWMS(A,i,j,k) which sorts in decreasing order the integers contained in an array A in the index range i : j (including i and j) using kway merge. After the completion of sorting the program should print A[i : j] starting from the new line: The sorted list in the range i:j is ........ Details: Please implement the program by strictly following these step. 1. Use three global arrays A,B,C. A contains the input sequence. B is used to form a MaxHeap, and C is used for temporary storage. 2. Let a = d(j i + 1)/ke,b = b(j i + 1)/kc,r = (j i + 1)%k (remainder of (j i + 1)÷k). Partition the array A[i : j] into A[i : i+a1],A[i+a : i+2a1],...,A[i+(r1)a : i+ra1],A[i+ra : i + ra + b],A[i + ra + b : i + ra + 2b],.... 3. In order to perform kway merge implement a MaxHeap on another array B. Let B be a 2D array with the range [0 : 1][1 : k]. To store integer x of subarray j by setting B[0][a] = x and B[1][a] = j. 4. To perform merge operation, ?rst enter the greatest element of each nonempty subarray into the heap, starting from the leftmost subarray (lower indices to the higher indices). Then each time the greatest element is extracted from the Heap, identify its subarray from B[][1] and insert the next element from that subarray into the heap. If that subarray becomes empty, then no insertion will occur. MaxHeap

must be implemented exactly the way we discussed in the class. Use HeapSize to keep track of the number of elements currently in the heap. 5. The merge must be done into array C and then its content must be transferred back to A. 6. Take the array A and C lengths to be 1000 each. 7. To help us evaluate the correctness of the program, please print from a fresh line Content of the heap is B[0][1],B[0][2],...,B[0][k] after each extraction+insertion (or after extraction, if no insertion happens) in the heap. At the end of the routine KWMS(A,i,j,k) put a print statement which prints from a fresh line The sorted list in the range i : j is A[i],A[i + 1],...,A[j]. Note that this being a recursive program this statement will get printed after each recursive call.
