The Goal: Similar to the first project, this project also uses the random module in Python. The program will first randomly generate a number unknown to the user. The user needs to guess what that number is. (In other words, the user needs to be able to input information.) If the user’s guess is wrong, the program should return some sort of indication as to how wrong (e.g. The number is too high or too low). If the user guesses correctly, a positive indication should appear. You’ll need functions to check if the user input is an actual number, to see the difference between the inputted number and the randomly generated numbers, and to then compare the numbers.• Concepts to keep in mind: • Random function• Variables• Integers• Input/Output• Print• While loops• If/Else statements
Answers
Answer:
Here is the Python program:
import random #to generate random numbers
def generateRandNo(): #function to generate random number
randNo = random.randint(1,100) #generates random number in range from 1 to 100
return randNo #returns the generated random number
def userInput(message = "Guess the number "): #to gets integer input from user and return the input number
userGuess = int(input(message)) #store the int type input from user in userGuess variable
return userGuess #returns the user input number
def compareNumbers(userGuess,randNo): #compares the user input with actual randomly generated number
if userGuess > randNo: # if user input is greater than actual number
return "The number is too high"
elif userGuess < randNo: #if user input is less than actual number
return "The number is too low"
else: #if user guess is correct
return "Correct"
def main(): #main method
correct = False #sets correct to False
begin = True #sets start game i.e. begin to True
while correct or begin: #while loop keeps repeating as long as user guess is correct or user wants to start game again
guessCount = 0 #counts number of trials user takes to guess the correct number
randNo = generateRandNo() #generates a random number using generateRandNo
userGuess = userInput() #gets input number from user using userInput method
guessCount+=1 #increments at each guess made by user
message = compareNumbers(userGuess,randNo) #compares user guess input number with actual number
while message != "Correct" : # while message is not equal to Correct
print(message) #prints to guess the number
userGuess = userInput("Try again: ") #keeps asking user to try again and enter a number
guessCount = guessCount + 1 #increments guessCount by 1 at each guess made by user
message = compareNumbers(userGuess,randNo) #compares user input with actual number
print()
print(message,"It took you ",guessCount," attempts to answer\n") #prints how much trials user took to guess correct number
choice = input("Do you wish to continue? (Enter yes or no) ") #asks user if user wants to start over
if choice == 'no': # if user enters no
exit(1) #exits the program
else: #if user enters yes starts the game again
correct = True #sets correct guess to True
main() #calls main method to start the guess game
Explanation:
The program is well explained in the comments attached with each line of the code. Suppose the randomly generated number (actual number) is 50 and user input is 24 then message The number is too low is displayed and if user guess input is 80 then The number is too high is displayed. If the user guesses the correct number i.e. 50 3rd time then the message displayed is:
It took you 3 attempts to answer.
The the user is asked to continue as:
Do you wish to continue? (Enter yes or no)
If user enters no the program exits if yes then user is asked to Guess the number again.
The screenshot of output is attached.

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
Answers
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.

Explanation:
Implement a class Balloon that models a spherical balloon that is being filled with air. The constructor constructs an empty balloon. Supply these methods:
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.
Answers
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

Create an HTML form that will accept four fields: pet name, pet ID, pet weight, and birthdate. Name this file petInfo.html. There should be a submit and reset button on your html form. Your input fields for your form should be inside of a table. The submit button should send the data to a php file named updateInfo.php. The updateInfo.php file should check the data submitted by the html file for proper formatting. While it is allowable that you may check input on the client side (either HTML or Javascript), you MUST check for valid input on the server using PHP.
***IMPORTANT***
Your POST variables in your HTML file must be labeled as follows. I have written an automated script to run tests on your code, and it depends on the POST variables being labeled correctly within the HTML Form.
1) "pet_name"
2) "pet_id"
3) "pet_weight"
4) "birth_date"
The following rules must be enforced by your PHP script about the input.
• No field is allowed to be blank.
• Maximum length of pet name is 20 characters.
• Pet ID must be 4 lowercase letters followed by 3 numbers. Example: abcd123
• Max length of pet weight is 7 characters. Max of two digits after decimal point. Must be a positive value. Range: 0.00 – 9999.99.
• The name should be only made up of alphabetical characters. (no numbers or symbols).
• Birthdate should be in the format 1/1/2002. Examples of valid input: 01/01/2002, 12/1/1999, 12/25/2015. Do not allow: 12/25/02 (The whole year should appear in the input).
If all the fields are valid, your PHP script should save the data into a file named petInfo.txt which should have the following format, and be sorted by "pet_name". Put each record on its own line. To simplify things, you can assume that Names are unique - i.e. you can use the name as a key for your associative array. (I won't use two of the same name when I test your code).
PetName, PetID, PetWeight, PetBirthDate\n
Once the new data has been received, you should also display ALL data that has been entered into the text file from your PHP script into an HTML table. The table should be sorted by last name just like the text file. After successfully displaying your table, create a link back to the petInfo.html page.

Create a class named FormLetterWriter that includes two overloaded methods named displaySalutation(). The first method takes one String parameter that represents a customer's last name, it displays the salutation "Dear Mr. or Ms." followed by the last name. The second method accepts two String parameters that represent a first and last name, and it displays the greeting "Dear" followed by the first name, a space, and the last name. After each salutation, display the rest of a short business letter: "Thank you for your recent order." Write a main() method that tests each overloaded method. Save the file as FormLetterWriter.java.

{
System.out.println("Dear Mr. or Ms. " + last_Name);//print value
}
static void displaySalutation(String first_Name, String last_Name) //overload the method displaySalutation
{
System.out.println("Dear " + first_Name + " " + last_Name);//print value
}
public static void message()//defining a method message
{
System.out.println("Thank you for your recent order.");//print message
}
public static void main(String[] args) //defining main method
{
displaySalutation("I Kell");//calling a method displaySalutation by passing a single String value
message();//calling message method
displaySalutation("Christ", "John");//calling a method displaySalutation by passing a two String value
message();//calling message method
}
}
Output:
please find the attached file.
Explanation:
In the above given program a calss "FormLetterWriter" is defined, in side the class we perform the method overloading, in which a method "displaySalutation" is used in first definition it accepts a single string variable "first_Name", and in second time, it accept two string variable " first_Name and last_Name".
Inside the both method, we use print method, that print its value, and an onther method message is defined, that print the given message.
In the class main method is declared, in which we apply mathod overloading and also call the message method for print the given business letter.

Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800:
1. Let y be the year (such as 1800 or 2001).
2. Divide y by 19 and call the remainder a. Ignore the quotient.
3. Divide y by 100 to get a quotient b and a remainder c.
4. Divide b by 4 to get a quotient d and a remainder e.
5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder.
6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient.
7. Divide c by 4 to get a quotient j and a remainder k.
8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder.
9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient.
10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder.
11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient.
Then Easter falls on day p of month n. For example, if y is 2001:
a = 6 h = 18 n = 4
b = 20, c = 1 j = 0, k = 1 p = 15
d = 5, e = 0 m = 0
g = 6 r = 6
Therefore, in 2001, Easter Sunday fell on April 15. Write a program that prompts the user for a year and prints out the month and day of Easter Sunday.

Using programming concepts, the option that is NOT a reason to include comments in a code is:
a. Comments help the computer decide whether certain components of a program are important.
-------------------------
Usually, codes are very long, and each person is responsible for a part of the problem. The parts have to be intervened with each other, and thus, sometimes a programmer will have to look at another part of the code, not coded by him. Thus, for the programmer and other people working in the project to understand, comments are important.Additionally, the comments are used to help the programmers debug their own code, as they can go part by part and see what is done in each part, also helping them work throughout the development process.In a program, there may be some components that end up not being necessary, but this is not decided by comments, and thus, option A is not a reason to include comments in programs.A similar problem is given at https://brainly.com/question/13527834

Compare these timings to the theoretical timings the algorithm binary search provides. Are there differences between the three programs? Explain your timings and observations!!

The code to this question can be defined as follows:
Explanation:
C language code:
#include <stdio.h>//defining header file
int binarySearch(int x[], int l, int y, int z)//defining method binarySearch that accepts four integer parameter
{
if (y >= l)//defining if block that check r value is greater the l
{
int m= l + (y - l)/2; //defining if block that holds mid value of array
if (x[m] == z)//use if block that check value in array
return m;// return array value
if (x[m] > z) //defining if block that check array value greater then x value
return binarySearch(x, l, m-1, z);//use return keyword to call method
return binarySearch(x, m+1, y, z);// in else it use return keyword to call method
}
return -1;//return value -1
}
int main()//defining main method
{
int x[] = {2, 3, 4, 10, 40};//defining array that hold integer values
int n = sizeof(x)/ sizeof(x[0]);//use n variable to hold its size value
int z = 10;//defining x varaiable that hold integer value
int r= binarySearch(x, 0, n-1, z);//use r varaiable to hold method return value
if(r== -1) //defining if block that check its value equal to -1
printf("Number is not foud in array ");//print message
else
printf("Number is present at %d position", r);//print value
return 0;
}
C++ language code:
#include <iostream>// header file
using namespace std;
int binarySearch(int x[], int l, int y, int z)//defining method binarySearch that accepts four integer parameter
{
if (y >= l)//defining if block that check r value is greater the l
{
int m= l + (y - l)/2; //defining if block that holds mid value of array
if (x[m] == z)//use if block that check value in array
return m;// return array value
if (x[m] > z) //defining if block that check array value greater then x value
return binarySearch(x, l, m-1, z);//use return keyword to call method
return binarySearch(x, m+1, y, z);// in else it use return keyword to call method
}
return -1;//return value -1
}
int main()//defining main method
{
int x[] = {2, 3, 4, 10, 40};//defining array that hold integer values
int n = sizeof(x)/ sizeof(x[0]);//use n variable to hold its size value
int z = 10;//defining x varaiable that hold integer value
int r= binarySearch(x, 0, n-1, z);//use r varaiable to hold method return value
if(r== -1) //defining if block that check its value equal to -1
cout<<"Number is not foud in array ";//print message
else
cout<<"Number is present at position "<< r;//print value
return 0;
}
Python language code:
def binarySearch (a, x, r, y):#defining a method binarySearch
if r >= x:#defining if block that checks r is greater than equal to x
m = x + (r - x)//2#defining m variable that hold mid value
if a[m] == y:#use if that check its input value equal y
return m#return m value
elif a[m] > y:#use array that check its value greaterthan y
return binarySearch(a,x, m-1, y) #use return keyword to call method
else:#defining else block
return binarySearch(a, m+1, r, y)#use return keyword to call method
else: #defining else block
return -1#return value -1
a = [ 2, 3, 4, 10, 40 ]#defining list a that holds value
y = 10#defining integer variable
r = binarySearch(a, 0, len(a)-1, y)#defining r variable that holds method value
if r != -1:#use if that check r is not equal to -1
print ("Number is available at ", r," position")#print value
else:#else block
print ("Number is not available in array")#print message

Explanation:
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
#necessary to import file
import sys
#define function
def palindrome(s):
return len(s) > 1 and s == s[::-1]
def main():
if len(sys.argv) < 3:
print('Problem reading the file')
exit(1)
file_input = sys.argv[1]
file_output = sys.argv[2]
try:
with open(file_input, 'r') as file open(file_output, 'w') as w:
for raw in file:
raw = raw.strip()
#call function
if palindrome(raw.lower()):
w.write(raw + "\n")
except IOError:
print("error with ", file_input)
if __name__ == '__main__':
main()
