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 simple java delcaration for an array of double values name a. Do not allocate space for the elements of the array.

import numpy as np a = np.array([1,2,3]) b = np.array([4,5,6]) You may need to use NumPy methods to answer the following questions. What is the cross product of the two vectors a and b given above? What is the dot product of the two vectors a and b given above?

You are given an array-like data structure Listy which lacks a size method. It does, however, have an elementAt ( i) method that returns the element at index i in 0( 1) time. If i is beyond the bounds of the data structure, it returns -1. (For this reason, the data structure only supports positive integers.) Given a Listy which contains sorted, positive integers, find the index at which an element x occurs. If x occurs multiple times, you may return any index.  Write code with explanation

Using JAVA, write a method that swaps two rows of a two-dimensional array. The row indices to be swapped are passed as parameters to the method (Assume row indices are valid indices). Write a test program to demonstrate correct operation of the method.

this is insturction Write a program which prompts the user to enter up to 15 floating point numbers (terminated with a non-numeric), reads them into an array, then prints the following. The program must use an array (not a vector) to get credit. The array values in the original order, separated by commas, with no trailing comma at the last value. The array values where the order of each adjacent pair of elements is swapped, separated by commas (NOT every element swapped with its next neighbor, which would just move the first element to the end, but every original pair swapped only in that pair. For an odd element count, the last element should not change. See examples below.) The smallest number in the array. Example program outputs with user input shown in bold font: Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 # Original array: 1, 0, -1.001 The swapped array: 0, 1, -1.001 Smallest number: -1.001 Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 5 ,…

Write an c progra, that takes an array of N integers (N will be specified by the user at run time). It then finds how many numbers in the array are divisible by 3 and how many numbers are divisible by 7.   the it copies, from the input array above, the numbers that are divisible by 3 into a new array and those divisible by 7 into a different new array. Once copied, the algorithm should compute the average of each of these two new arrays and print the averages on the screen with suitable message to let the user know which average is being printed   Note: an integer number is divisible by 3 (respectively 7) if the remaining of its division by 3 (respectively 7) is 0. You are allowed to use the modulus operator %.

In java Define and create a 2-dimensional array of integers with 4 rows and 8 columns. Print the elements of the array in table format (rows and columns). Replace the element in the second row and third column of the array with the value 99.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…

Given an array arr of type int, along with two int variables i and j, write some code that swaps the values of arr[i] and arr[j]. Declare any additional variables as necessary.
