Exercise 2. We have seen that Dijkstra's algorithm can be implemented in two ways: Variant (a) uses an array to store the dist] values of the unknown nodes, and Variant (b) uses a MIN-HEAP to store these values. (a) Suppose in your application m <3n. Which variant gives a faster runtime? Justify your answer. (b) Suppose in your application m2 n²/3. Which variant gives a faster runtime? Justify your answer.

In java code, write MERGE SORT algorithm that uses LOCALITY AWARENESS. For example if int[] a = {3, 0, 4, 1, 5, 2, 9, 7, 8, 6} and int d = 3, then after mergeSort a should equal {0,1 ,2 3, 4, 5, 6, 7, 8, 9}. The runtime for the implementation should be no worse than O(N*log(d)). We know that no element will move more than d positions. Function header and parameters are as follows: public static void mergeSort(int[] a, int d) { // TO BE IMPLEMENTED }
Analyze the Time Complexity. Show your solution and the corresponding Big-O notation.
Suppose you have m sorted arrays, each with n elements, and you want to combine them into a single sorted array with mn elements. 1. If you do this by merging the first two arrays, next with the third, then with the fourth, until in the end with the last one. What is the time complexity of this algorithm, in terms of m and n? 2. Give a more efficient solution to this problem, using divide-and-conquer. What is the running time?

Hello, i need help with understanding Big-O. What is the execution time Big-O for each of the methods in the Queue-1.java interface for the ArrayQueue-1.java and CircularArrayQueue-1.java implementations? Short Big-O reminders: Big-O is a measure of the worst case performance (in this case execution time). O(1) is constant time (simple assignment statements) O(n) is a loop that iterates over all of the elements. O(n2) is one loop nested in another loop, each of which iterates over all the elements. If a method calls another method, what happens in the called method must be taken into consideration. Queue.java public interface Queue<E> { /** * The element enters the queue at the rear. */ public void enter(E element); /** * The front element leaves the queue and is returned. * @throws java.util.NoSuchElementException if queue is empty. */ public E leave(); /** * Returns True if the queue is empty. */ public boolean…
Write an algorithm called ArrayColumnSum(A[0..n-1, 0..n-1], B[0..n-1 ]) which takes asinput, one n x n matrix A and a list B of size n and outputs B such that B[k] as the sum of theelements of column k of A.
Implement MERGE-SORT() algorithm that reads from a file named “inputHW02.txt” a list of double numbers (max =3,000,000 numbers), sorts those numbers and indicates time consumption. This programming question will address theadvantage of using iteration loops over recursive calls as well as using INSERTION-SORT() as a procedure in MERGESORT().Your program must perform the following actions:1. Opens the given file name and reads all double numbers. For simplicity, we assume this file only containsnumbers and nothing else.2. Implements the function INSERTION-SORT() that only sort an array of maximum 25 numbers. The idea is thatINSERTION-SORT() will be used as a sub-procedure to sort any sub-array when its size is small enough.3. Four versions of MERGE-SORT() namelya. MERGE-SORT-A(): Using recursive calls and NO INSERTION-SORT() as a sub-procedureb. MERGE-SORT-B(): Using ITERATIVE loops (i.e, NO recursion) and NO INSERTION-SORT() as a subprocedure.c. MERGE-SORT-C(): Using recursive calls…

Now let's examine a Dynamic Program algorithm to solve this problem. 3.3 Let's say we have an array of length X+1. How would we define array[x]? or What is array[x] defined for?
Consider the following problem:L is a sorted list containing n signed integers (n being big enough), for example [-5, -2, -1, 0, 1, 2, 4] (here, nhas a value of 7). If L is known to contain the integer 0, how can you find the index of 0 ?
Say we want to assign guests to tables at a party. Each table has a maximum number of guests who can sit there, and each guest has a list of other guests they are unwilling to sit with. Briefly explain how we could use a stack and backtracking to find a universally acceptable assignment of guests to tables.
