Select the for-loop which iterates through all even index values of an array. A. for(int idx = 0; idx < length; idx++) B. for(int idx = 0; idx < length; idx%2) C. for(int idx = 0; idx < length; idx+2) D. for(int idx = 0; idx < length; idx=idx+2)

Prompt: In python langauge, write a function that adds a random noise to all elements of a NumPy array Code: import numpy as np import math import matplotlib.pyplot as plt import pandas as pd def addNoise(inputArray): modifiedArray = np.zeros(len(inputArray)) #YOUR CODE HERE: return(modifiedArray) def test(): inputs = np.arange(-5, 5,0.2) outputs = addNoise(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs, 'black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()

Refer to the following method that finds the smallest value in an array. /** Precondition: arr is initialized with int values. * Oparam arr the array to be processed Greturn the smallest value in arr public static int findMin(int[] arr) { int min = /* some value */; int index = 0; while (index < arr.length) { if (arr [index] < min) min = arr [index]; index++; } return min; } Which replacement(s) for /* some value */ will always result in correct execu- tion of the findMin method? I Integer.MIN_VALUE II Integer.MAX_VALUE III arr [0] (A) I only (B) II only (C) III only (D) I and III only (E) II and III only

An array int[] intArray can be initialized during its definition by A.) It can't be initialized B.) by writing int[] intArray = {1.0f}; C.) by writing int[] intArray = {0,1,2}; D.) by writing int[0-10] intArray = {0,1,2,3,4,5,6,7,8,9};

Prompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array. Code: import numpy as np import math import matplotlib.pyplot as plt import pandas as pd def sigmoid(inputArray): modifiedArray = np.zeros(len(inputArray)) #YOUR CODE HERE: return(modifiedArray) def test(): inputs = np.arange(-100, 100, 0.5) outputs = sigmoid(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs,'Black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()

What does each line of code mean?

JAVA Programming Write a function that returns true if you can partition an array into one element and the rest, such that this element is equal to the product of all other elements excluding itself. Examples canPartition ([2, 8, 4, 1]) → true // 8 = 2 x 4 x 1 canPartition ([-1, -10, 1, -2, 20]) → false canPartition ([-1, -20, 5, -1, -2, 2]) true
