QUESTION 19 Assume the following array definitions: import numpy as np integers = np.array([[1, 2, 3], [4, 5, 6]]) floats = np.array([0.0, 0.1, 0.2, 0.3, 0.4]) Which of the following statements a), b) or c) is false? O a. You can view an array's total number of elements with the attribute size and the number of bytes required to store each element with itemsize. O b. The array integers' size is the product of the shape tuple's values two rows of three elements each for a total of six elements. O c. In each case, itemsize is 8 because integers contains int64 values and floats contains float64 values, which each occupy 8 bytes. O d. All of the above statements are true.

23. What are the values of the elements in the array numbers after the following code is executed? int[] numbers = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100}; for (int i =1, i < 10; 1++) { numbers[i] = numbers [i - 1]; }

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

Let numbers be an array defined as follows. int numbers[5][7]; Assume that the array has been filled with values. Which of the following blocks of code calculates the row totals of the 2-dim array and store them in the 1-dim array named totals? int totals[5] = {0}; for (int row = 0; row < 5; ++row) { int total = 0; for (int col = 0; col < 7; ++col) { total += numbers[row][col]; } totals[row] = total; } int totals[7] = {0}; for (int col = 0; col < 7; ++col) { int total = 0; for (int row = 0; row < 5; ++row) { total += numbers[row][col]; } totals[col] = total; } O None of these int totals[7] = {0}; for (int row = 0; row < 7; ++row) { int total = 0; for (int col = 0; col < 5; ++col) { total += numbers[row][col]; } totals[row] = total; }

QUESTION 17 Assume the following array definitions: import numpy as np integers = np.array([[1, 2, 3], [4, 5, 6]]) floats = np.array([0.0, 0.1, 0.2, 0.3, 0.4]) Which of the following statements a), b) or e) is false? O a. The array function determines an array's element type from its argument's elements. O b. You can check the element type with an array's dtype attribute. O c. For performance reasons, NumPy is written in the Java programming language and uses Java's data types. O d. All of the above statements are true.

d) Print all the elements of the array that are greater than the previous element at smaller than the next element. The first and the last element should be excluded. int arr[] = {5,14,66,7,22,39,0,-12,23,91}

QUESTION 18 Assume the following array definitions: import numpy as np integers = np.array([[1, 2, 3], [4, 5, 6]]) floats = np.array([0.0, 0.1, 0.2, 0.3, 0.4]) The attribute dimensions: contains an array's number of dimensions and the attribute contains a specifying an array's O a. dim, size, list O b. ndim, shape, tuple O c. dim, size, tuple O d. ndim, shape, list

Given the following array definition int nums[5] = {1, 2, 3};what will the following statement display?cout << nums[3];

Q_8. Decription:- Given an array of integers, write a PHP function to find the maximum element in the array. PHP Function Signature: phpCopy code function findMaxElement($arr) { // Your code here } Example: Input: [10, 4, 56, 32, 7] Output: 56 You can now implement the findMaxElement function to solve this problems. .
