- Create a template class for a Matrix(2d array) and write the following functions in it. 1. Print the left diagonal 2. Print the right diagonal 3. Print specified row 4. Print specified column 5. Print overall matrix.(Sum elements row by row) write a method that returns the sum of all the elements in a specified row in a matrix using the following header: public static double sumRow(double [][] m, int rowIndex) Write a test program that reads a 3-by-4 matrix and displays the sum of each row here is a sample run.please answer all questions You need to generate a (5x12) rain matrix (Rain[5][12]) that contains the average rainfall over 12 months for a 5 year period. You program should do the following steps: 1) Create a 5x12 integer rainfall matrix 2) Create a 5 element array of int pointers(int * Rain[5]) and assign each pointer to the address of the first element of each row 3) Populate the elements of the matrix with pseudo-random numbers having a range from 0-100 inches. Use the rand( ) function to generate your temperatures. The output of rand() should be mod with 100 (rand()%100) in order to get reasonable rainfall values. Init the random number generator with long seed = srand(67) This task should be performed by a function, void RainGen(int* Rain[ ], int R, int C), that populates all the matrix entries. 4) After generating all rainfall matrix entries, print the entire matrix using the function, void Print(int* Rain[ ], int R, int C); 5) Calculate the…
- Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…(Java) Suppose we have a 2D array of integers called matrix. Write a code to initialize the array matrix with random values between 0-99.Write a program in C that will find the largest number from a 4X4 matrix and divide each element of the odd columns of that matrix by that largest number and store in a new matrix then print the matrix. Take inputs from user. Use the following prototype:void normalizeMatrix(int rowSize, int colSize, float mat[rowSize][colSize])void printMatrix(int rowSize, int colSize, float mat[rowSize][colSize])
- in c++. Write a function that returns the sum of all the elements in a specified column in a matrix using the following header: const int SIZE = 4; double sumColumn(double m[][SIZE], int rowSize, int columnIndex); Write a test program that reads a 3-by-4 matrix and displays the sum of each column. please leave comments on each step.For this project you will be implementing a new data structure called LinkedGrid. This is a linked type data structure version of a 2D array. The LinkedGrid can support any combination of dimensions (n x n, n x m, or m x n, where n > m) This data structure has a singly linked system which allows you to traverse the grid in multiple directions in addition to allowing you to retrieve specific rows and columns. The following diagram gives a rough visual of this data structure. NOTE: Your LinkedGrid MUST work with any number of nodes, the picture only shows twelve as an idea. You may not hardcode only twelve nodes... There should be no public functions other than the ones given to you You may implement any other private functions you feel are necessary to help you implement the given constructors / public functions Complete ALL methods with "TO DO" in LinkedGrid.java import java.util.ArrayList; public class LinkedGrid<E>{private int numRows;private int numCols; private…given an array of integer values , return true if 6 appears as either the first or last element in the array. firstLast6([1,2,36]) true firstLast([6,1,2,3]) true firstLast([13,6,1,2,3]) false
- What is the time complexity associated with accessing a single value in an array? The Vector class is clearly more complex than the array. What is the time complexity of accessing an element with the get method?h) A new element can be added in a const array in Javascript. True/FalseTake input an integer n from user which is the size of a n*n matrix. Then take input n2 integers which are the elements of the matrix. Print the actual matrix and then convert the actual matrix to its transpose and print it again. Note: Modify the actual matrix here. C++ language.
