Consider the int Array below and determine the values of A and B so that Array[0] has an integer in the range [-23, 71] Array[0] = A + rand() % B;

Please type so that i can read you solution

Declare and initialize an array as such, int arr[] = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1); Considering the following code snippet, what value does 'arr' have after the function call 'arrayTest(arr);'? 1 void arrayTest(int a[]){ 2 3 4 5 } for (int i = 0; i<10; i+= 2) { a[i] = i; 0123456789 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 02468 } 0927456381 Question 33 (1 point) Suppose that strl, str2, and str3 are string variables. After the following statements execute, the value of str3 is " strl1 = "abc"; str2 = "xyz"; abc xyz str3= strl + 1_1 + str2; abc-xyz C++ xyz-abc

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?

What does the array arr contain after the following code segment is executed? Show the content of the entire array for full credit int[] arr = new int[8]; arr[1] arr[3] arr[7] = 3; = 11; 5; int x arr[1] + 1; %3D 44; arr[x] arr[arr[7]] = 7;

Define the array printed below using the np.array() function, and assign it to the variable 'my_array' (only one line of code needed). [[0, 2, 4],[9, -6, 5],[0, 0, -10]]

Return the maximum value from the provided integer array. You may assume that all values in the array will be non-negative. getMax([1]) → 1getMax([0, 3, 2, 12, 4]) → 12getMax([15, 3, 1, 7, 2]) → 15 public int getMax(int[] nums) { Write your code in here using this outline.}

May you please explain each line I starred and why they have these output values. Thank you!

We have an array variable ‘var’ int var[4] = {25,20,30,40}; Find the memory address of the first element of in the array: var[0]

In [ ]: We obtained an array with N = 10 values, scattered about mean of 25 (mm). Let's calculate the mean, standard deviation, standard deviation of the mean and 20-uncertainty SL of these numbers. In the following code, do these steps: • In the first cell, add a brief comment that explains what each statement does. Start each comment with a # sign. • In the second cell, delete the raise Not ImplementedError() code line and print the standard deviation and 20-uncertainty on the screen (follow the example for mean_L) mean_L = np.mean (L) print("Mean length: ", mean_L) stddev_L = np. std (L, ddof=1) stddev_mean_L = stddev_L/np.sqrt(N) uncertainty_L = 2*stddev_mean_L In [ ] V #YOUR CODE HERE raise NotImplementedError() #calculates the mean of L In the above code, the green expressions on the right hand side, such as np.mean, np. std and np.sqrt are functions built into the numpy package of Python. The names on the left hand side are variable names invented by me.

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.
