While exercising, you can use a heart-rate monitor to see that your heart rate stays within a safe range suggested by your trainers and doctors. According to the American Heart Association (AHA) (www.americanheart.org/presenter.jhtml?identifier=4736), the formula for calculating your maximum heart rate in beats per minute is 220 minus your age in years. Your target heart rate is a range that is 50–85% of your maximum heart rate. [Note: These formulas are estimates provided by the AHA. Maximum and target heart rates may vary based on the health, fitness and gender of the individual. Always consult a physician or qualified health care professional before beginning or modifying an exercise program.] Create a class called HeartRates. The class attributes should include the person’s first name, last name and date of birth (consisting of separate attributes for the month, day and year of birth). Your class should have a constructor that receives this data as parameters. For each attribute provide set and get functions. The class also should include a function getAge that calculates and returns the person’s age (in years), a function getMaxiumumHeartRate that calculates and returns the person’s maximum heart rate and a function getTargetHeartRate that calculates and returns the person’s target heart rate. Since you do not yet know how to obtain the current date from the computer, function getAge should prompt the user to enter the current month, day and year before calculating the person’s age. Write an application that prompts for the person’s information, instantiates an object of class HeartRates and prints the information from that object—including the person’s first name, last name and date of birth—then calculates and prints the person’s age in (years), maximum heart rate and target-heart-rate range

Python is a high-level, interpreted programming language that was first released in 1991. It is named after the Monty Python comedy group and was created by Guido van Rossum. Python is known for its readability, simplicity, and ease of use. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming.

Here's a solution in Python to the problem statement:

def print_arrow(body, head):

   for i in range(1, body + 1):

       print("1" * i)

   for i in range(head, 0, -1):

       print("1" * i)

body = int(input("Enter body size: "))

head = int(input("Enter head size: "))

print_arrow(body, head)

This code takes two integers as input, representing the size of the arrow body and arrowhead. The function print_arrow takes these two values as parameters and uses nested for loops to print the arrow. The first for loop prints the body of the arrow, while the second for loop prints the head of the arrow.

This program reads in 9 double values from the user via standard input, and it assigns the first value to the variable largestval. It then loops through the remaining 8 values and checks each one to see if it's larger than largestval. If it is, then it updates the value of largestval. Finally, it prints the largest value that was read in.

What is an example of largestval?

Directory Listing is the correct response. The web folder of an application contains a list of all the files and subdirectories. This reveals application flaws with Directory Listing.

a subfolder is a computerised organisational directory that is nested inside another directory. Sections of your main website can be divided using subdirectories, which are content subfolders. Each subfolder shares the top-level domain (TLD) of your website, and its URL structure always follows the root domain. Examples of subdirectories include all of the following: example.com/shop. The subdirectory appears in a URL after the root directory or domain name.  Therefore, hubspot.com/pricing might be a subfolder URL. Alternatively, it may be something more challenging like pricing/sales.hubspot.com.

Option a is correct. If a hard link is created to a file and the original file is deleted, the original file will be deleted, but the contents of the file can still be accessed using the hard link.

By default, the ln command creates hard links. Use the -s option to create soft (symbolic) links. The -f option forces the command to overwrite existing files.

A hard link has the same inode number as the original file, so it points to the same disk space as the original file. The content of the hard link remains the same even if the original file is renamed. A hard link is basically a link to the actual content of the original file.

Even if the user removes one of the hard links, the data is still accessible through the other remaining links. When the user deletes all shortcuts and no process has the file open, the operating system frees up the space occupied by the file.

The function select takes a list and a function as input parameters, applies the function to each element of the list, and returns a new list containing only those elements for which the function returns true.

Below is the implementation of select function in python programming.

def select(lst, func):

   return [x for x in lst if func(x)]

This function takes a list lst and a function func as parameters. It applies the func to each element of the lst using a list comprehension and returns a new list containing only those elements for which the func returns true.

To use the select function to find prime numbers from a list, we can define the is_prime function as follows:

def is_prime(n):

   if n <= 1:

       return False

   for i in range(2, int(n**0.5) + 1):

       if n % i == 0:

           return False

   return True

Then, we can call the select function with the list and the is_prime function as follows:

lst = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

result = select(lst, is_prime)

print(result)

This will output: [2, 3, 5, 7], which are the prime numbers in the list.

Answer:85

Explanation:

In Binary, we have 8 bits, all powers of 2, going up to 128.

When you only have 7 digits, you just add 0's to the left until it's 8. So in this case it would 01010101. Each 0 means the bit is "off," and each 1 means the bit is "on."

The 1st bit, from left to right, equals 128. The next is 64, then 32, then 16, then 8, then 4, then 2, then 1.

Since this specific number is alternating between bits, we know it is:

64 + 16 + 4 + 1 = 85

Since these are the bits that are turned on. Hope this helps!

ArrayList<Seat> mySeats = new ArrayList<>();

trainSeats.add(new Seat());

trainSeats.get(0).reserve("John", "Smith", 44);

Explanation:

ArrayList<Seat> mySeats = new ArrayList<>();

This declares a reference variable called mySeats for an ArrayList of Seat objects and initializes it as an empty list.

trainSeats.add(new Seat());

This adds a new element of type Seat to an ArrayList called trainSeats. The new Seat object is created using the default constructor.

trainSeats.get(0).reserve("John", "Smith", 44);

This uses method chaining to get the element at index 0 in ArrayList trainSeats and call the reserve method on it with arguments "John", "Smith", and 44. This makes a reservation for John Smith, who paid $44.
