The function leap n, which takes an integer n as input, and returns True if the year n is a leap year, and False otherwise. NOTE: Please provide function declaration [2 marks]. Leap years are those that are evenly divisible by 4, except any year that is also evenly divisible by 100 unless that year is also evenly divisible by 400. So, for example, 1996, 2012, and 2020 are all leap years, but 2100, 2200, and 2300 are not leap years, because although they are all evenly divisible by 4, they are also evenly divisible by 100. However, 1600, 2000, and 2400 are leap years, because although they are divisible by 100, they are also divisible by 400. The Haskell interaction may look like: > leap 1996 True > leap 2000 True > leap 2100 False

Answer:

Explanation:

The following code snippet is a leap year checker written in Haskell which checks to see if the year is a leap year and then outputs a boolean value.

isDivisibleBy :: Integral n => n -> n -> Bool

isDivisibleBy x n = x `rem` n == 0

leap_n :: Integer -> Bool

leap_n year

 | divBy 400 = True

 | divBy 100 = False

 | divBy   4 = True

 | otherwise = False

where

  divBy n = year `isDivisibleBy` n

StreamPal is an audio-streaming application for mobile devices that allows users to listen to streaming music and connect with other users who have similar taste in music. After downloading the application, each user creates a username, personal profile, and contact list of friends who also use the application.

The application uses the device’s GPS unit to track a user’s location. Each time a user listens to a song, the user can give it a rating from 0 to 5 stars. The user can access the following features for each song that the user has rated.

A list of users on the contact list who have given the song the same rating, with links to those users’ profiles
A map showing all other users in the area who have given the song the same rating, with links to those users’ profiles
A basic StreamPal account is free, but it displays advertisements that are based on data collected by the application. For example, if a user listens to a particular artist, the application may display an advertisement for concert tickets the next time the artist comes to the user’s city. Users have the ability to pay a monthly fee for a premium account, which removes advertisements from the application.

Which of the following statements is most likely true about the differences between the basic version and the premium version of StreamPal?

Group of answer choices
a. Users of the basic version of StreamPal use less data storage space on their devices than do users of the premium version of StreamPal.
b. Users of the basic version of StreamPal are more likely to give songs higher ratings than are users of the premium version of StreamPal.
c. Users of the basic version of StreamPal indirectly support StreamPal by allowing themselves to receive advertisements.
d. Users of the basic version of StreamPal spend more on monthly fees than do users of the premium version of StreamPal.

A large computer repair company with several branches around Texas, TexTech Inc. (TTi), is looking to expand their business into retail. TTi plans to buy parts, assemble and sell computer equipment that includes desktops, monitors/displays, laptops, mobile phones and tablets. It also plans to sell maintenance plans for the equipment it sells that includes 90-day money back guarantee, 12-month cost-free repairs for any manufacturing defects, and annual subscription for repairs afterwards at $100 dollars per year. As part of a sales & marketing campaign to generate interest, TTi is looking to sell equipment in 5 different packages: 1. Desktop computer, monitor and printer 2. Laptop and printer 3. Phone and tablet 4. Laptop and Phone 5. Desktop computer, monitor and tablet TTi plans to sell these packages to consumers and to small-and-medium businesses (SMB). It also plans to offer 3-year lease terms to SMB customers wherein they can return all equipment to the company at the end of 3 years at no cost as long as they agree to enter into a new 3-year lease agreement. TTi has rented a warehouse to hold its inventory and entered into contracts with several manufacturers in China and Taiwan to obtain high-quality parts at a reasonable price. It has also hired 5 sales people and doubled its repair workforce to meet the anticipated increase in business. TTi has realized that it can no longer use Excel spreadsheets to meet their data and information needs.

The bag class in Chapter 5 has a new grab member function that returns a randomly selected item from a bag (using a pseudorandom number generator). Suppose that you create a bag, insert the numbers 1, 2, and 3, and then use the grab function to select an item. Which of these situations is most likely to occur if you run your program 300 times (from the beginning): A. Each of the three numbers will be selected about 100 times. B. One of the numbers will be selected about 200 times; another number will be selected about 66 times; the remaining number will be selected the rest of the time. C. One of the numbers will be selected 300 times; the other two won't be selected at all.

Write the simulate method, which simulates the frog attempting to hop in a straight line to a goal from the frog's starting position of 0 within a maximum number of hops. The method returns true if the frog successfully reached the goal within the maximum number of hops; otherwise, the method returns false. TheFrogSimulationclass provides a method calledhopDistancethat returns an integer representing the distance (positive or negative) to be moved when the frog hops. A positive distance represents a move toward the goal. A negative distance represents a move away from the goal. The returned distance may vary from call to call. Each time the frog hops, its position is adjusted by the value returned by a call to thehopDistance method. g

Create a class called Dot for storing information about a colored dot that appears on a flat grid. The class Dot will need to store information about its position (an x-coordinate and a y-coordinate, which should both be integers) and its color (which should be a string for now). You can choose what to call your attributes, but be sure to document them properly in the class's docstring.

Don't forget that every function definition, including method definitions, must have a docstring with a purpose statement and signature.

Consider the following method:
public static String joinTogether(int num, String[] arr)
{
String result = "";

}

The following code appears in another method in the same class:
String[] words = {"dragon", "chicken", "gorilla"};
int number = 4;
System.out.println(joinTogether(number, words));

If you have downloaded this book's source code from the companion Web site, you will find a file named text.txt in the Chapter 12 folder. (The companion Web site is at www.pearsonhighered/gaddis.) The text that is in the file is stored as on sen- tence per line. Write a program that reads the file's contents and calculates the average of words per sentence.

Write a program which simulates the result of a person choosing 3 objects in a random order out of a box containing 3 objects in total. The box contains the following 3 objects: apple, ball, cat. A single selection pass of your program describes the random selection of 3 objects out of the box, without replacement. This means that a particular object can only be selected from the box once. At the beginning of a pass, the box is full, so it contains all 3 objects. After an object is selected from the box, your program will print the name of the object and then choose another object without replacing the previous object. The selection process repeats 3 times until the box is empty

How SPARQL 1.1 has advantage over SPARQL 1.0??​

Suppose a program is supposed to reverse an array. For example, if we have the array arr = {1, 2, 3, 4, 5}, after reversing the array we would have arr = {5, 4, 3, 2, 1}.

Most of the code for the program is shown here:
Const int SIZE = 5;
int arr[SIZE] = {1, 2, 3, 4, 5};
int firstindex =0, lastindex = SIZE-1, temp;

1 _______________________________

{
temp = arr[firstindex];
arr[firstindex] = arr[lastindex];
arr[lastindex] = temp;
firstindex++;
lastindex--;
}

All of the following options below could be correctly inserted at line 1 in the code shown above EXCEPT:

a. while(firstindex < lastindex)
b. while(firstindex <= lastindex)
c. for(int i=0; i<(SIZE/2-1); i++)
d. for(int i=0; i<(SIZE/2); i++)

6.22 LAB: Output values below an amount - methods
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value. Assume that the list will always contain less than 20 integers.

Ex: If the input is:

5 50 60 140 200 75 100
the output is:

50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a space, including the last one.

Such functionality is common on sites like Amazon, where a user can filter results.

Write your code to define and use two methods:
