Implement a method
public static double[] add(double[] a, double[] b)
for the component-wise sum of
For example, the result of applying add to (0, 3, −1) and (2, −5, 1) should be (0 + 2, 3 + (−5), −1 + 1) = (2, −2, 0).
Important: add should NOT change the given arrays and should return a new array instead.

- FOR JAVA Write a Java method that takes two 2 dimensional int arrays (a and b) and a 2 dimensional boolean array (c) where all three arrays have the same size. Your method should return an array (result) such that, if a partic- ular element in c is true, then the corresponding (same indexed) element in result must be the multiplication of the the corresponding elements of a and b. If the element in c is false, then the the corresponding element in result must be the negative of multiplication of the the corresponding element in a and b. For example ifa = {{1,2,3},{4,5}},b = {{1,2,1},{0,2}} andc = {{true,false,true},{false,true}}, then the result should be result={{1, -4, 3}{0, 10}}.Write a Java method that takes two 2 dimensional int arrays (a and b) anda 2 dimensional boolean array (c) where all three arrays have the samesize.

If the element in c is false, then the the corresponding elementin result must be the negative of multiplication of the the correspondingelement in a and b.write a java program that outputs a walk, trail, path, closed walk, circuit, and cycle of a given directed graph matrix. That matrix is to be hard coded as such... There are 4 vertices in this directed graph. We know that because there are 4 rows and 4 columns. If there is a 1 that means that the vertex on the left (you need to name them) has an arrow edge towards the vertex on the top. If there is a 2 that means there are two directed edges in the same direction going from the left vertex to the vertex on the top. If there is a 0 that means there are no edges from the vertex on the left to the top vertex. 1 2 2 1 2 1 2 1 2 2 1 2 1 1 1 0 - Make sure to program the matrix in to your code. - Output an example of each, make sure they are labeled. (6 outputs ) Example of a directed graph matrix below. The red numbers around the matrix are the vertices. If there is a 0 it means there is no edge from the vertex on the right to the vertex on the top.
- Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.)Write a program that reads two matrices of integers. It then generates the sum, difference and productof the two matrices.The sum of the two matrices of the same size is a matrix with elements that are the sums of thecorresponding elements of the two given matrices. Addition is not defined for matrices of different sizes.If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, tosubtract matrix B from matrix A, we simply subtract corresponding elements.To multiply a matrix by another matrix we need to do the "dot product" of rows and columns. The "DotProduct" is where we multiply matching members, then sum up:(1, 2, 3) • (7, 9, 11) = 1×7 + 2×9 + 3×11 = 58We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the3rd members (3 and 11), and finally sum them up.a Java method that takes an array of primitive integers as its only parameter and returns the centered average of that list as a primitive double. The centere average is defined for this question as the average of all the values in the array except for the largest and smallest values. If smallest or largest value occurs more than once, disregard only one copy of each as appropriate. the length of the array is at least 3 and every location in the array has been assigned a value
- Write a Java program to find continuous sub array of the given array whose sum is equal to a given number. For example, If {12, 5, 31, 9, 21, 8} is the given array and 45 is the given number, then you have to find continuous sub array in this array such that whose elements add up to 45. In this case, {5, 31, 9} is such sub array whose elements add up to 45.Write a Java method that will take in a generic ArrayList with Doubles (reference type). Have the method take each Double and convert it to an Integer and store it into another generic ArrayList that holds Integers. When done, return the new Integer ArrayList.Please help. How to solve this on Java language by using only Dynamic Programming? Thank you. We are given a set A of integers. Check whether we can partition A into three subsets with equal sums. It is important to note that all elements should be included in the equally divided subsets; no element should be left out, and none of the elements should be repeated in the subsets.For example: A={4,7,6,2,10,7,10,2} has such a partition: {4,2,10}, {7,7,2},{6,10}Input: A set, A, of integersOutput: if we can partition A into three subsets with equal sums, print subsets otherwise present a suitable message.
- A set of integers 0..MAX may be implemented using an array of boolean values. This particular implementation is called a bit-vector implementation of a Set. Since C doesn’t have the Boolean data type, then substitute TRUE with 1 and FALSE with 0, or define 1 and 0 as TRUE and FALSE, respectively.For example, if the integer 3 is an element of the set, then the array element indexed by 3 is TRUE. On the other hand, if 3 is not an element, then the array element indexed by 3 is FALSE. For example, if the integer 3 is an element of the set, then the array element indexed by 3 is TRUE. On the other hand, if 3 is not an element, then the array element indexed by 3 is FALSE.For example: if s = {3,4,6,8}, the array looks like this: Implement a programmer-defined data type called BitSet to represent a set as follows:typedef int BitSet[MAX];Implement the following functions:void initialize(BitSet s); - set all array elements to FALSEvoid add(int elem,BitSet s);- set the item indexed by elem to…For this problem I have a java code: import java.util.Arrays; import java.util.Scanner; public class MergeSortWeightedSumInversion { public static long merge(int arr[], int l, int mid, int r) { long weight = 0; int n1 = mid-l+1; int n2 = r-mid; int[] a = new int[n1]; int[] b = new int[n2]; for(int i = 0; i < n1; i++) { a[i] = arr[l+i]; } for(int i = 0; i < n2; i++) { b[i] = arr[mid+i+1]; } int i = 0, j = 0, k = l; while(i<n1 && j<n2) { if(a[i] <= b[j]) { arr[k] = a[i]; k++; i++; } else { weight += (a[i] + b[j]); arr[k] = b[j]; k++; j++; } } while(i<n1) { arr[k] = a[i]; k++; i++; } while(j<n2) { arr[k] = b[j]; k++; j++; } return weight; } public static long mergeSort(int arr[], int l, int r) { long weight = 0; if(l < r) { int mid = (l+r)/2; weight += mergeSort(arr, l, mid); weight += mergeSort(arr,mid+1,r); weight += merge(arr,l,mid,r); } return weight; } public static void main(String[] args) { Scanner scan = new Scanner(System.in); int n; n =…Given two arrays A and B of equal size N, the task is to find a vector containing only those elements which belong to exactly one array - either A or B - but not both.
