Define a function named reverse() that accepts an array of strings and display it in the reverse order. Example: Given the array: $a=array(“apple”,”orange”,”banana”,”kiwi”) The function must display: kiwi banana  orange   apple 2. Create an array and call the function reverse()

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.

//convert array of numbers from farenheit to celcius// example:// argument: [23, 32, 41, 50, 59]// return: [-5, 0, 5, 10, 15]// hint: use Array.mapfunction toCelcius(array){ } //write a function that takes an input array and returns an array of booleans (>=75) or fail (<75)// example:// argument: [20, 30, 50, 80, 90, 100]// return: [false, false, false, true, true, true]// hint: use Array.mapfunction passOrFail(array){ }

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()

# dates and times with lubridateinstall.packages("nycflights13") library(tidyverse)library(lubridate)library(nycflights13) Qustion: Create a function called date_quarter that accepts any vector of dates as its input and then returns the corresponding quarter for each date Examples: “2019-01-01” should return “Q1” “2011-05-23” should return “Q2” “1978-09-30” should return “Q3” Etc. Use the flight's data set from the nycflights13 package to test your function by creating a new column called quarter using mutate()

Describe how to pass an array as a parameter to a function.

use c++ Programming language  Write a program that creates a two dimensional array initialized with test data.  Use any data type you wish .  The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal:  This function should accept a two dimensional array as its first argument and an integer as its second argument.  The second argument should be the subscript of a column in the array. The function should return the total of the values in the specified column. .getHighestInRow: This function should accept a two…

javascript only: This quarter, your team manager is awarding commission to anyone who closes a sale worth $15,000 or more! The commission amount will be 10% of the value of their largest sale. Anyone who does not make this large of a sale will receive the base commission of $500. Write a function `salesCommission(arr)` that takes an array of objects containing salesperson names and their largest sale, and returns the total amount of commission money that needs to be paid out to the team. Example: salespeople = [ { name: "Susan", largestSale: 3000 }, { name: "Brianna", largestSale: 20000 }, { name: "Dwayne", largestSale: 13000 }, { name: "Delilah", largestSale: 26000 }, { name: "Fernando", largestSale: 8000 }, ]; console.log(salesCommission(salespeople)); // 6100
