dont give the same solution again .10 min left fast Array creation: There are various ways to create arrays in NumPy. O For example, you can create an array from a regular Python list or tuple using the array function. The type of the resulting array is deduced from the type of the elements in the sequences. O Often, the elements of an array are originally unknown, but its size is known. Hence, NumPy offers several functions to create arrays with initial placeholder content. These minimize the necessity of growing arrays, an expensive operation. For example: np.zeros, np.ones, np.full, np.empty, etc. O To create sequences of numbers, NumPy provides a function analogous to. range that returns arrays instead of lists. O arange: returns evenly spaced values within a given interval. step size is specified. O linspace: returns evenly spaced values within a given interval. num no. of elements are returned. O Reshaping array: We can use reshape method to reshape an array. Consider an array…

Question 3: An array listA is called balanced if it stores the same count of even and odd integers. Write a program to test an array listA filled with 10 integers {22,5,18,4, 9,12,13,17, 23,24}. Then the program will output the integers stored in listA and from initializer list an as follow: checks if the array listA is balanced or not. Sample Run: listA store: (22 5 18 4 9 12 13 17 23 24} listA is a balanced array am
narmts Save Answer Write a Java program that uses ArrayList and Iterator. It should input from user the names and ages of your few friends in a loop and add into ArrayList. Finally, it should use Iterator to display the data in a proper format. (Hint- Lecture 02: Slide 8) Sample output: List of my Friends Enter name and age [friend# oj Khalid Al-shamri 22.5 Do you want to add another friend (y/n)? y Enter name and age [friend# 1] Rahsed Al-anazi 21.1 Do you want to add another friend (y/n)? y Enter name and age [friend# 2] Salem Al-mutairi 23.7 Do you want to add another friend (y/n)? n Here is the data you entered: 0. Khalid Al-shamri, 22.5 1. Rahsed Al-anazi, 21.1 2. Salem Al-mutairi, 23.7
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()
Kotlin Programming Array Exercise Create a Kotlin program that can print a specified element in an array given the code below: fun main(){ val pets=arrayOf("dog","cat","bird") for(element in pets){ println(element + " ") } } Thanks for answer I need it now how do we print the 2nd element?
Problem Name: Two Sum Problem Description: Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can assume that the input array is not sorted. Thanks.
