For activities with output like below, your output's whitespace (newlines or spaces) must match exactly. See this note. Write code that outputs variable num_books as follows. End with a newline. Ex: If the input is 3, then the output is: Books: 3 1 123456 2 Our tests will run your program with input 3, then run again with input 6. Your program should work for any input, though. *** 3 num_books = input() Your code goes here

You've decided to test the wifi speed in the classroom at the beginning of every lecture. Create a program that will tell you if the wifi speed over the past 3 classes has increased, decreased, or neither. If the wifi speeds are sorted and increasing, then print out "The wifi is getting faster!". If the wifi speeds are sorted and decreasing, then print out "The wifi is getting slower!". If the wifi speeds are unsorted or if two or more speeds are the same, then print "The wifi speed is changing unpredictably." The user should input 3 non-negative numbers (double) separated by spaces. Sample runs: Enter wifi speeds over the last 3 classes: 162 180 225 The wifi is getting faster! Enter wifi speeds over the last 3 classes: 37.5 21.2 19.9 The wifi is getting slower! Enter wifi speeds over the last 3 classes: 162 135.3 225 The wifi speed is changing unpredictably. Ensure you are doing basic input validation, output Please enter a valid input. if the user inputs a negative wifi speed. Make…
Create a card game in which the dealer shuffles the deck and deals 13 cards to the player. The player sorts her hand and says whether it includes the King of Hearts. Repeat 4 times so all the cards are dealt eventually. Internally, the player should return true or false without writing to the console. In response, the dealer should write on the console, "You won!" or "You loose again."
You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code…
In this assignment you will demonstrate your knowledge of debugging by fixing the errors you find in the program below. Fix the code, and paste it in this document, along with the list of the problems you fixed.This example allows the user to display the string for the day of the week. For example, if the user passed the integer 1, the method will return the string Sunday. If the user passed the integer 2, the method will return Monday. This code has both syntax errors and logic errors. Hint: There are two logic errors to find and fix (in addition to the syntax errors).Inport daysAndDates.DaysOfWeek;public class TestDaysOfWeek {public static void main(String[] args) {System.out.println("Days Of week: ");for (int i = 0;i < 8;i++) {System.out.println("Number: " + i + "\tDay Of Week: " + DaysOfWeek.DayOfWeekStr(i) )}}}package daysAndDatespublic class DaysOfWeek {public static String DayOfWeekStr(int NumberOfDay) {String dayStr = ""switch (NumberOfDay) {case 1:dayStr =…

Write code that reads in a value for variable numCucumbers and then outputs as follows. End with a newline. Ex: If the input is 9, then the output is: The store has 9 cucumbers. /Our tests will run your program with input 9, then run again with input 6, then again. Your program should work for any input, though.
Input a number n and print out n lines of text in the pattern below, shown for example n = 5 * * * * 1 * * * 2 1 * * 3 2 1 * 4 3 2 1 5 4 3 2 1 There is exactly one space between numbe4rs, there is no space at the end of each line, and each line ends with a newline. The first two tests will ignore the whitespace.
Write a program that asks the user to enter an integer number and checks whether the number is prime or not. Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 . . . ) is a natural number greater than 1 that has no positive divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not.
This must be written in the programming language Coral and able to run on the Coral simulator: https://corallanguage.org/simulator/ I've been trying to figure this out for days and I'm no closer than when I started. Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Ex: When the input is 15 20 0 5 -1, the output is: 10 20
You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause “wear and tear” on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print(“Current Lap is: “ , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car…
