Consider a list L = {387, 690, 234, 435, 567, 123, 441}. Here, the number of elements n = 7, the number of digits l = 3 and radix r = 10. This means that radix sort would require 10 bins and would complete the sorting in 3 passes. Algorithm to illustrates the skeletal procedure for the LSD first radix sort.
Write a bottom-up mergesort that makes use of the array's order by carrying out the following steps each time it needs to locate two arrays to merge: locate the first element in an array that is smaller than its predecessor, then locate the next, and finally merge them to form a sorted subarray. Consider the array size and the number of maximal ascending sequences in the array while analysing the running time of this method.
Please can someone explain xs and ys and these Haskell statements I can’t understand
Using Java, 1. Implement external sort: for sort phase use normal sort, for merge phase use two way merge to merge n sorted files (merge2way(n)), for array sort use heapsort. Also write merge(f1, f2, f3) to merge two sorted files f1 and f2 into f3.. Write mergenway(n) method and print execution time of both merges for initial input file over 10MB data. A sample input is as follow:Note:Fist input is max array size for sort 10 84 82 52 80 96 85 75 75 82 87 92 89 57 94 93 92 63 99 87 72 73 56 74 50 84 62 72 55 86 75 74 100 83 60 53 68 89 67 66 65 72 94 73 54 98 96 85 75 75 82 87 92 89
Write a bottom-up mergesort that makes use of the array's order by carrying out the following steps each time it needs to locate two arrays to merge: locate the first entry in an array that is smaller than its predecessor, then locate the next, and finally merge them to form a sorted subarray. Consider the array size and the number of maximal ascending sequences in the array while analysing the running time of this algorithm.
Consider an array A containing elements 12, 23, 18, 19, 2,7, 8 starting from index 0 to 6. What will be the sum of the middle three values after the second pass of the merge procedure in the merge sort algorithm?
Apply Merge sort and Quick to sort the list, C, O,M,P,I,L,O,R in alphabetical order?

(a) In what cases should Merge Sort be used? In what cases is it not efficient? Explain.(b) The following is an implementation of merge and mergeSort - Making sure to take note of the added print statement in merge, what would the following call in main print to the screen? int[] a = {4, 3, 2, 1};int[] temp = new int[a.length];mergeSort(a, 0, a.length-1, temp);
Dr. Sponge thinks it's too hard to implement Merge. So, he wants to replace Merge with Insertion Sort (yes, the insertion sort you learned in class). The following is the pseudo-code of the new Merge-Sort, Merge-Sort(p, r) 1. if p == r return 2. q = floor of (p+ r) / 2 3. Merge-Sort(p, q) 4. Merge-Sort(q+1, r) 5. Insertion-Sort(p, r) Give the recurrence for the running time of this new Merge-Sort and solve it. We let T(n) denote the running time when input array has n elements. By solving the recurrence (no need to show how you solved it), we obtain T(n) =
Write the Java code for the merge part of the merge sort.
