What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?

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()

10 Build the Sudoku Reviewer ( the testing program). The specification is below. Please note: you DO NOT have to build a Sudoku solver. To test you just need to build a class that generates a 9x9 2D array with the values you want to test. You can assume the value types are valid. (integers from 1-9). 1-The main purpose is to make sure the Sudoku solver actually solved it correctly! 2- You are also confirming the solver solves puzzle in no longer than a minute 3- Solver (not the reviewer) requires 7 INDICES (ELEMENTS) filled in the input array at least. 4- The reviewer receives both the original puzzle and the solution. The Reviewer needs to confirm the solution is not only a valid SudoKu solution but also the solution to the original puzzle. 5- Solver will return a 2d array filled with -1s if input array has an error/bad input (exception). Reviewer will check for this case.

query the user for the size of an array of integers build an array of integers and fill it with random integer values. The values will range between 0 and 100 display the array clone the array display the cloned array sort the cloned array display the original array and the sorted cloned array create another array that is double the size of the cloned array and copy the data from the cloned array into the new array. Then fill the remaining cells in the new array with random values. These will also range between 0 and 100.Note: int[] newArray = new int[clone.lenght*2] Write program in jva

Return the First Element in an Array JavaScript Create a function that takes an array containing only numbers and return the first element. Examples getFirstValue ([1, 2, 3]) → 1 getFirstValue ([80, 5, 100])→ 80 getFirstValue ([-500, 0, 50])-500
