Answer:
Unlike when you create a String, when you create a StringBuilder, you must use the keyword new
Explanation:
Strings are used in programming which also opens the way for StringBuilder to be used too. In javascript, for instance, variables are useful for storing data, We have "Let" and "const" variables. Const variables cannot be changed after they’re created. The data stored are in types an example is a string. Strings allow one to write a value and store the result in a variable.
For example, using the dot operator, when you:
console.log('love'.length); // Prints 4
Note that console.log() allows the computer to evaluate the expression inside the parentheses and print that result to the console.
.length prints 4 as the result. This shows how the string has a property that stores the number of characters in that string.
StringBuilder with the keyword "new" is used when we want to change or modify data property stored in a string.

What is one reason to create a study check list
Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.
Answer:
current_members = [28, 0, 7, 100]
member_id = 7
if member_id in current_members:
is_a_member = True
else:
is_a_member = False
print(is_a_member)
Explanation:
Although it is not required I initialized the current_members list and member_id so that you may check your code.
After initializing those, check if member_id is in the current_members or not using "if else" structure and "in" ("in" allows us to check if a variable is in a list or not). If member_id is in current_members, set the is_a_member as True. Otherwise, set the is_a_member as False.
Print the is_a_member to see the result
In the example above, since 7 is in the list, the is_a_member will be True

Explanation:
It is generally believed that a digital citizen refers to a person who can skillfully utilize information technology such as accessing the internet using computers, or via tablets and mobile phones, etc.
Kiosks (digital kiosks) are often used to market brands and products to consumers instead of having in-person interaction. Interestingly, since almost everyone today goes shopping, consumers who may have held back from using digital services are now introduced to a new way of shopping, thus they become digital citizens sooner or later.

Write a program that will print out statistics for eight coin tosses. The user will input either an "h" for heads or a "t" for tails for the eight tosses. The program will then print out the total number and percentages of heads and tails. Use the increment operator to increment the number of tosses as each toss is input. For example, a possible sample dialog might be: For each coin toss enter either ‘h’ for heads or ‘t’ for tails. First toss: h Second toss: t Third toss: t Fourth toss: h Fifth toss: t Sixth toss: h Seventh toss: t Eighth toss: t Number of heads: 3 Number of tails: 5 Percent heads: 37.5 Percent tails: 62.5
Answer:
Written in Python
head = 0
tail = 0
for i in range(1,9):
print("Toss "+str(i)+": ")
toss = input()
if(toss == 'h'):
head = head + 1
else:
tail = tail + 1
print("Number of head: "+str(head))
print("Number of tail: "+str(tail))
print("Percent head: "+str(head * 100/8))
print("Percent tail: "+str(tail * 100/8))
Explanation:
The next two lines initialize head and tail to 0, respectively
head = 0
tail = 0
The following is an iteration for 1 to 8
for i in range(1,9):
print("Toss "+str(i)+": ")
toss = input() This line gets user input
if(toss == 'h'): This line checks if input is h
head = head + 1
else: This line checks otherwise
tail = tail + 1
The next two lines print the number of heads and tails respectively
print("Number of head: "+str(head))
print("Number of tail: "+str(tail))
The next two lines print the percentage of heads and tails respectively
print("Percent head: "+str(head * 100/8))
print("Percent tail: "+str(tail * 100/8))

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.
Answer:
The Following are the code to this question:
def cost(miles, milesPerGallon, dollarsPerGallon):##defining a method cost that accepts three parameter
return miles / milesPerGallon * dollarsPerGallon# calculate cost and return it value
milesPerGallon = float(input('Enter miles/Gallon value: '))#defining variable milesPerGallon for user input
dollarsPerGallon = float(input('Enter dollars/ Gallon value: '))#defining variable dollarsPerGallon for user input
print('{:.5f}'.format(cost(10, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.5f}'.format(cost(50, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.3f}'.format(cost(400, milesPerGallon, dollarsPerGallon)))#call method and print its value
Output:
Enter miles/Gallon value: 20.0
Enter dollars/ Gallon value: 3.1599
1.57995
7.89975
63.198
Explanation:
In the above-given code, a method "cost" is defined, that accepts three value "miles, milesPerGallon, and dollarsPerGallon" in its parameter, and use the return keyword for calculating and return its value.
In the next step, two variable "milesPerGallon, and dollarsPerGallon" is declared, that use the input method with float keyword for input floating-point value.
After input value, it uses a print method with different miles values, which are "10,50, and 400", and input value to pass in cost method to call and print its return value.

An example of an access control is a: Multiple Choice Check digit. Password. Test facility. Read only memory.
Answer:
B. Password
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication is like an access control, ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
An example of an access control is a password because it is typically a basic and fundamental front-line defense mechanism against an unauthorized use of data or cyber attacks from hackers.

This can be achieved by the use of the Arabic numbering system, Roman numerals or use of bullets.
Answer:
C : It includes levels and sublevels of information
Explanation:
Create a function min_mid_max which takes a list as its formal parameter and returns a new list with the following characteristics: element 0 contains the minimum value • element 1 contains the middle value (not the median -- which would require an average if the list had an even number of elements). If the list is even (e.g. [1,2,3,4]) the 'middle' value will be the right value of the two possible choices (e.g. 3 rather than 2). • element 2 contains the maximum value Notes: • You can only use Python syntax shown so far (even if you know more) • You cannot use any math library (we have yet to see this) • You should use the function sorted. Remember the function sorted does not change its input, it returns a new list. • You should only need to call sorted one time. print(sorted(3,2,1])) • You can use the function int (another built in function) to help determine the index of the middle value. This function takes a floating point (or any kind of number) and converts it into an integer (e.g.print(int(4.32)). This will allow you to treat lists with an even number of elements the same as a list with a odd number of elements. • If min_mid_max is called with an empty list, return an empty list. • If min_mid_max is called with 1 item that item is the min, mid, and the max • If min_mid_max is called with 2 items, the mid and the max should be the same • No need to worry about the incoming list being the value None
Answer:
Follows are the code to this question:
def min_mid_max(myList):#defining a method min_mid_max that accept a list in parameter
if len(myList)==0:#defining if block that check list length equal to 0
return []#return empty list
s = sorted(myList)#defining variable s that uses the sorted method to sort the list
m = int(len(myList)/2)#defining mid variable that hold list mid value
return [s[0], s[m], s[-1]]#return list values
print(min_mid_max([1,2,3,4]))#use print function to call method
print(min_mid_max([]))#use print function to call method
print(min_mid_max([1, 2]))#use print function to call method
print(min_mid_max([1]))#use print function to call method
Output:
Please find the attached file.
Explanation:
In the given code, a method "min_mid_max" is defined, which accepts a list "myList" in parameter, inside the method if block is used, that check length of the list.
If it is equal to 0, it will return an empty list, otherwise, a variable "s" is declared, that use the sorted method to sort the list, and in the "m" variable, it holds the mid number of list and returns its value.
In the print method, we call the above method by passing a list in its parameter.

Write a program named palindromefinder.py which takes two files as arguments. The first file is the input file which contains one word per line and the second file is the output file. The output file is created by finding and outputting all the palindromes in the input file. A palindrome is a sequence of characters which reads the same backwards and forwards. For example, the word 'racecar' is a palindrome because if you read it from left to right or right to left the word is the same. Let us further limit our definition of a palindrome to a sequence of characters greater than length 1. A sample input file is provided named words_shuffled. The file contains 235,885 words. You may want to create smaller sample input files before attempting to tackle the 235,885 word sample file. Your program should not take longer than 5 seconds to calculate the output
In Python 3,
MY CODE: palindromefinder.py
import sys
def is_Palindrome(s):
if len(s) > 1 and s == s[::-1]:
return true
else:
return false
def main():
if len(sys.argv) < 2:
print('Not enough arguments. Please provide a file')
exit(1)
file_name = sys.argv[1]
list_of_palindrome = []
with open(file_name, 'r') as file_handle:
for line in file_handle:
lowercase_string = string.lower()
if is_Palindrome(lowercase_string):
list_of_palindrome.append(string)
else:
print(list_of_palindrome)
If you can adjust my code to get program running that would be ideal, but if you need to start from scratch that is fine.
Open your python-3 console and import the following .py file

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]); switch ranforce case 0 disp('There is no wind') case {1,2,3,4,5,6} disp('There is a breeze') case {7,8,9} disp('This is a gale') case {10,11} disp('It is a storm') case 12 disp('Hello, Hurricane!') end
Answer:

12.18 Lab - Structs
In this lab, you will familiarize yourself with structs through a small exercise. We will be mixing the RGB values of colors together to make a new one.
RGB stands for red, green and blue. Each element describes the intensity value ranging from 0 - 255. For example: black color will have RGB values (0, 0, 0) while white will have (255, 255, 255).
Create an array of structs color. The struct contains three integers named red, green and blue. This corresponds to the RGB values of a color. For each array element, ask the user to enter the intensity value of red, green and blue. The value should be between 0 and 255 (inclusive).
*********The user can enter at most 10 colors. ********. see below for inputs
Additionally, compute the average of each of the red, green and blue components. For code modularity, implement a function that returns the average of each rgb component in your dynamic array. The function (called average) should take in a struct array, the rgb type for which you want to compute the average (as a string - red, blue or green) and its length. Print out the final result in the form (r, g, b), where r, g, b corresponds to each averaged value.
Can you guess what color you mixed? (Note: Your program does not need to print the final color mixed)

void addAir(double amount) adds the given amount of air.
double getVolume() gets the current volume.
double getSurfaceArea() gets the current surface area.
double getRadius() gets the current radius.
Supply a BalloonTester class that constructs a balloon, adds 100cm^3 of air, tests the three accessor methods, adds another 100cm3 of air, and tests the accessor methods again.
Answer:
Here is the Balloon class:
public class Balloon { //class name
private double volume; //private member variable of type double of class Balloon to store the volume
public Balloon() { //constructor of Balloon
volume = 0; } //constructs an empty balloon by setting value of volume to 0 initially
void addAir(double amount) { //method addAir that takes double type variable amount as parameter and adds given amount of air
volume = volume + amount; } //adds amount to volume
double getVolume() { //accessor method to get volume
return volume; } //returns the current volume
double getSurfaceArea() { //accessor method to get current surface area
return volume * 3 / this.getRadius(); } //computes and returns the surface area
double getRadius() { //accessor method to get the current radius
return Math.pow(volume / ((4 * Math.PI) / 3), 1.0/3); } } //formula to compute the radius
Explanation:
Here is the BalloonTester class
public class BalloonTester { //class name
public static void main(String[] args) { //start of main method
Balloon balloon = new Balloon(); //creates an object of Balloon class
balloon.addAir(100); //calls addAir method using object balloon and passes value of 100 to it
System.out.println("Volume "+balloon.getVolume()); //displays the value of volume by getting value of volume by calling getVolume method using the balloon object
System.out.println("Surface area "+balloon.getSurfaceArea()); //displays the surface area by calling getSurfaceArea method using the balloon object
System.out.println("Radius "+balloon.getRadius()); //displays the value of radius by calling getRadius method using the balloon object
balloon.addAir(100); //adds another 100 cm3 of air using addAir method
System.out.println("Volume "+balloon.getVolume()); //displays the value of volume by getting value of volume by calling getVolume method using the balloon object
System.out.println("Surface area "+balloon.getSurfaceArea()); //displays the surface area by calling getSurfaceArea method using the balloon object
System.out.println("Radius "+balloon.getRadius()); } } //displays the value of radius by calling getRadius method using the balloon object
//The screenshot of the output is attached.
