Write a program that teaches arithmetic to a young child. The program tests addition and subtraction. In level 1, it tests only addition of numbers less than 10 whose sum is less than 10. In level 2, it tests addition of arbitrary one digit numbers (which means that the sum could be more than 10). In level 3, it tests subtractions of one digit numbers with a non-negative difference. Generate random numbers for each of the levels based on its requirements, and get players answers as their response. Verify if the user entered the correct answer. The player will start at level 1, and gets up to two tries per problem. Advance from one level to the next when the player has achieved a score of five points (one point per successful answering the question).

In the QuickSort algorithm, the partition method we developed in class chose the start position for the pivot. We saw that this leads to worst case performance, O(n2), when the list is initially sorted. Try to improve your QuickSort by choosing the value at the middle, instead of the value at the start, for the pivot. Test your solution with the Driver you used for homework.

Answers
Answer:
Answered below
Explanation:
#file is first opened and saved into file_object variable.
file_object = open('new_file.txt', 'r')
file_contents = file_object.readlines()
#the readlines() reads the contents of the file, line by line and returns a list of lines. Therefore, file_contents contains a list of lines read from file object and can be iterated over to get each line.
1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.

Replace the comment with:
cout<<100 + rand() % 49<<endl;
cout<<100 + rand() % 49<<endl;
Explanation:
To generate random number from min to max, we make of the following syntax:
min + rand()%(max - min)
In this case:
[tex]min = 100[/tex]
[tex]max = 149[/tex]
So, we have:
100 + rand()%(149 - 100)
100 + rand()%49
To print the statements, make use of:
cout<<100 + rand() % 49<<endl;
cout<<100 + rand() % 49<<endl;
A video game character can face toward one of four directions: north, south, east, and west. Each direction is stored in memory as a sequence of four bits. A new version of the game is created in which the character can face toward one of eight directions, adding northwest, northeast, southwest, and southeast to the original four possibilities. Which of the following statements is true about how the eight directions must be stored in memory?
A. Four bits are not enough to store the eight directions. Five bits are needed for the new version of the game.
B. Four bits are enough to store the eight directions
C. Four bits are not enough to store the eight directions. Sodeen bits are needed for the new version of the game.
D. Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.
Answers
Answer:
B. Four bits are enough to store the eight directions
Explanation:
The summary of the question is to determine whether 4 bits can store 8 directions or not.
To understand this question properly, the 8 bits will be seen as 8 different characters.
In computer memory, a computer of n bits can store 2^n characters.
In this case:
[tex]n = 4[/tex] i.e. 4 bits
So:
[tex]2^n = 2^4[/tex]
[tex]2^n = 16[/tex]
This implies that the memory can store up to 16 characters.
Because 16 > 8, then (b) answers the question.

Explanation:
Write a Python program (rainfall.py) to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. Then for each year, the program should ask twelve times, once for each month, for inches of rainfall for that month. At the end, , the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
Your program should contain two functions:
(1) rainfall(year): This function takes in a year (integer) as a parameter, and returns two values (totalMonths and totalRainfall). In this function, you need to use nested loop. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for inches (float) of rainfall for that month. After all iterations, the function should return the number of months (totalMonths) and the total inches of rainfall (totalRainfall). (Submit for 4 points)
(2) __main__: In the main, you do the following: (Submit for 6 points)
a. Prompt the user to input the number of years. Reprompt the user if the number of years is 0 or less. Hint: use a while loop.
b. Call rainfall(year) and pass to it the value entered above.
c. Calculate the average based on the returned values from rainfall function.
d. Display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
Answers
Answer:
def rainfall(year):
totalMonths = totalRainfall = 0
for y in range(year):
for month in range(12):
rainfall = float(input(f"Enter inches of rainfall for month #{month+1}: "))
totalRainfall += rainfall
totalMonths = year * 12
return totalMonths, totalRainfall
def __main__():
while True:
year = int(input("Enter the number of years: "))
if year > 0:
break
numberOfMonths, totalRainfall = rainfall(year)
averageRainFall = totalRainfall / numberOfMonths
print(f"\nTotal number of months: {numberOfMonths}")
print(f"The total inches of rainfall: {totalRainfall}")
print(f"The average rainfall per month for the entire period: {averageRainFall}")
if __name__ == '__main__':
__main__()
Explanation:
Create a function named rainfall that takes year as a parameter
Inside the function:
Create a nested for loop. The outer loop iterates for each year (The range is from 0 to year-1) and the inner loop iterates for each month of that year (The range is from 0 to 11). Inside the inner loop, ask the user to enter the rainfall for that month. Add the rainfall to the totalRainfall (cumulative sum)
When the loops are done, calculate the totalMonths, multiply year by 12
Return the totalMonths and totalRainfall
Inside the main:
Create a while loop that asks user to enter the number of years while it is greater than 0
Call the rainfall function, passing the year as parameter. Set the numberOfMonths and totalRainfall using the rainfall function
Calculate the averageRainFall, divide totalRainfall by numberOfMonths

Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec 31 is 365; for Jan 1 is 1, and for February 1 is 32. This program will ask the user to input day and month values. Then it will display the day number day number corresponding to the day and month values entered assuming a non-leap year. (See part II to this exercise below).
Answers
Answer:
In Python:
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
day = int(input("Day: "))
month = input("Month: ")
ind = months.index(month)
numday = 0
for i in range(ind):
numday+=daymonths[i]
numday+=day
print(numday)
Explanation:
This initializes the months to a list
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
This initializes the corresponding days of each month to a list
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
This gets the day from the user
day = int(input("Day: "))
This gets the month from the user
month = input("Month: ")
This gets the index of the month entered by the user
ind = months.index(month)
This initializes the sum of days to 0
numday = 0
This adds up the days of the months before the month entered by the user
for i in range(ind):
numday+=daymonths[i]
This adds the day number to the sum of the months
numday+=day
This prints the required number of days
print(numday)

Assume the data link protocol used by NDAS has the following associated characteristics:
An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte
Fill in the blanks
K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes
Answers
Answer:
The transmission speed = 0.278 MB/s
Explanation:
K = 8 bits
M = 11936/8 bits = 1492 bits
transmission rate R = 1000000/ 8 = 125000 bps
overhead bytes C = 20
probability = 0.01
time T = 30 ms = 30 x10^-3 s
The data transmission speed formula = K(M-C)(1-p) / (M/R) + T
= 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3
= 0.278 MB/s
