Please answer the below question for operating system using shell script. write a program in bash that has a user_defined function array_sum that takes each element of array as argument andcalculates their sum. At each step the sum will printed and then the final sum will be printed. For example:Input Array:[2 3 7 9]Output: 2 5 12 21final sum: 21

What is the best way to implement a dynamic array if you don't know how many elements will be added? Create a new array with double the size any time an add operation would exceed the current array size. Create a new array with 1000 more elements any time an add operator would exceed the current size. Create an initial array with a size that uses all available memory Block (or throw an exception for) an add operation that would exceed the current maximum array size.
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()
payment sent po 11:05 AM Received pasend nalang po yung question 11:06 AM pwede po ba with pic? 11:06 AM Opo 1 11:06 AM In C program Given a 2-Dimensional Array, sum up all the numbers that are not in the corners of the 2-D array. Example in the following 2-D Array: 5 7 1 6 2 6 1 8 1 5 4 7 5 8 9 1 4 4 5 1 I will not include those in the first and last row and those in the first and last column. I shall then only add 6+1+5+4+8+9 since all the other numbers are in the corner. To visualize: 5 7 1 6 2 6 1 8 1 5 4 7 5 8 9 1 4 4 5 1 Input 1. Number of Rows 2. Number of Columns 3. Elements of the 2-D Array Output Enter number of rows: 5 Enter number of columns: 4 Elements: 5 7 1 6 2 6 1 8 1 5 4 7 5 8 9 1 4 4 5 1 Sum = 33
