The Classic Triangle Testing Problem, (Myer's Triangle): A program reads three integer values. The three values are interpreted as representing the lengths of the sides of a triangle. The program prints a message that states whether the triangle is scalene, isosceles, or equilateral. Develop a set of test cases (at least 6 ) that you feel will adequately test this program. (This is a classic testing problem and you could find numerous explanations about it on the internet. I would recommend that you try to submit your own answer, based on your understanding of the topic)
Let’s define what the three different types of triangle requirements for the side’s lengths are:______.
Answer:
Here is the Python program:
def MyersTriangle(a, b, c): #method to test triangles
if not(isinstance(a, int) and isinstance(b, int) and isinstance(c, int)): #checks if values are of type int
return 'Enter integer values'
elif a==0 or b==0 or c==0: #checks if any value is equal to 0
return 'Enter integer values greater than 0'
elif a<0 or b<0 or c <0: #checks if any value is less than 0
return 'All values must be positive'
elif not (a+b>=c and b+c>=a and c+a>=b): #checks if triangle is valid
return 'Not a valid triangle'
elif a == b == c: #checks if triangle is equilateral
return 'triangle is equilateral'
elif a == b or b == c: #checks if triangle is isoceles
return 'triangle is isoceles'
elif a != b and a != c and b != c: #checks if triangle is scalene
return 'triangle is scalene'
#test cases
print(MyersTriangle(2.4,7.5,8.7))
print(MyersTriangle(0,0,0))
print(MyersTriangle(-1,5,4))
print(MyersTriangle(10,10,25))
print(MyersTriangle(5,5,5))
print(MyersTriangle(3,3,4))
print(MyersTriangle(3,4,5))
Explanation:
The program uses if elif conditions to check:
if the values are integers: this is checked by using isinstance method that checks if values belongs to a particular int. If this returns true then values are integers otherwise not
if values are not 0: this is checked by using logical operator or between each variable which checks if any of the values is 0
if values are not negative: This is checked by using relational operator < which means the values are less than 0
if values make a valid triangle: this is checked by the rule that the sum of two sided of the triangle is greater than or equal to the third side.
and then checks if the triangle is scalene, isosceles, or equilateral: This is checked by the following rules:
For scalene all three sides are unequal in length
For isosceles any of the two sides are equal in length
For equilateral all sides should be equal in length.
The screenshot of the program along with the output is attached.
Write a program that finds the number of items above the average of all items. The problem is to read 100 numbers, get the average of these numbers, and find the number of the items greater than the average. To be flexible for handling any number of input, we will let the user enter the number of input, rather than fixing it to 100.
Answer:
Written in Python
num = int(input("Items: "))
myitems = []
total = 0
for i in range(0, num):
item = int(input("Number: "))
myitems.append(item)
total = total + item
average = total/num
print("Average: "+str(average))
count = 0
for i in range(0,num):
if myitems[i] > average:
count = count+1
print("There are "+str(count)+" items greater than average")
Explanation:
This prompts user for number of items
num = int(input("Items: "))
This creates an empty list
myitems = []
This initializes total to 0
total = 0
The following iteration gets user input for each item and also calculates the total
for i in range(0, num):
item = int(input("Number: "))
myitems.append(item)
total = total + item
This calculates the average
average = total/num
This prints the average
print("Average: "+str(average))
This initializes count to 0
count = 0
The following iteration counts items greater than average
for i in range(0,num):
if myitems[i] > average:
count = count+1
This prints the count of items greater than average
print("There are "+str(count)+" items greater than average")

Write a program called DeliveryCharges for the package delivery service in Exercise 4. The program should again use an array that holds the 10 zip codes of areas to which the company makes deliveries. Create a parallel array containing 10 delivery charges that differ for each zip code. Prompt a user to enter a zip code, and then display either a message indicating the price of delivery to that zip code or a message indicating that the company does not deliver to the requested zip code.
Answer:
zip_codes = ["11111", "22222", "33333", "44444", "55555", "66666", "77777", "88888", "99999", "00000"]
charges = [3.2, 4, 1.95, 5.7, 4.3, 2.5, 3.8, 5.1, 6.6, 7.3]
deliver = False
index = -1
zip_code = input("Enter the zip code: ")
for i in range(len(zip_codes)):
if zip_code == zip_codes[i]:
deliver = True
index = i
break
if deliver:
print("The charge of delivery to " + zip_codes[index] + " is $" + str(charges[index]))
else:
print("There is no delivery to " + zip_code)
Explanation:
*The code is in Python.
Initialize the zip_codes array with 10 zip codes
Initialize the charges array with 10 corresponding values
Initialize the deliver as False, this will be used to check if the zip code is in the zip_codes
Initialize the index, this will be used if the zip code is a valid one, we will store its index
Ask the user to enter the zip_code
Create a for loop that iterates the length of the zip_codes array. Inside the loop:
Check if the zip_code is equal to the any of the items in the zip_codes. If it is, set the deliver as True, set the index as i, and break
When the loop is done, check the deliver. If it is True, then print the charge of the delivery. Otherwise, print that there is no delivery to that zip code

Write a function to receive any word as input, search the song titles only and return the number of top billboard songs that contain that word. Your function should meet the following requirements: Your function should receive any word or phrase as an input string and return a simple message with the number of songs that contain those words. E.g. [5] songs were found to contain [supplied phrase] in this dataset If the words or phrase supplied were not found in the database, return the message No songs were found to contain the words: [supplied phrase] Remember to deal with whatever letter case you are supplied i.e. all caps or all lowercase, etc. Test your function with the word like and confirm that your result reads [100] songs were found to contain [like] in this dataset
Answer:
Here is the function:
def NumberOfSongs(word): # function definition
count=0 #count the occurrence of word in song
for song in lyrics['Lyrics']: #iterates through song lyrics
if word in str(song): #if word is in the song
count=count+1 #adds 1 to the count
if count!=0: #if word occurs in the songs
return f'{str(count)} songs were found to contain {word} in this dataset' #display the count of the word in the song
else: #if word does not appear in any song
return f'No songs were found to contain the words:{word}' #returns this message if no songs were found with given word
print(NumberOfSongs('like')) #calls method with the word like given as parameter to it
Explanation:
You can add the csv file this way:
import pandas as pd
lyrics = pd.read_csv("lyrics.csv", encoding="cp1252")
Now you can use the NumberOfSongs method which iterates through the Lyrics of lyrics.csv and find if any of the songs in the file contains the specified word.
The screenshot of program along with its output is attached. Since the file was not provided i have created a csv file. You can add your own file instead of lyrics.csv

Define a function called sum, for a given an array and an int representing its size, if the size is at least 3, then sum up all elements whose indices are a multiple of 3 and return that value, otherwise, return 0.
Answer:
Written in C++
int sum(int arr[], int size) {
int total = 0;
if(size>=3) {
for (int i = 0; i < size; ++i) {
if(i%3 == 0) {
total += arr[i];
}
}
}
return total;
}
Explanation:
This line defines the function
int sum(int arr[], int size) {
This line initializes sum to 0
int total = 0;
This line checks if size is at least 3
if(size>=3) {
This loop iterates through the array
for (int i = 0; i < size; ++i) {
The following adds multiples of 3
if(i%3 == 0) {
total += arr[i];
}
}
}
This returns the calculated sum
return total;
}

Define a Python function named matches that has two parameters. Both parameters will be lists of ints. Both lists will have the same length. Your function should use the accumulator pattern to return a newly created list. For each index, check if the lists' entries at that index are equivalent. If the entries are equivalent, append the literal True to your accumulator. Otherwise, append the literal False to your accumulator.
Answer:
The function in Python is as follows:
def match(f1,f2):
f3 = []
for i in range(0,len(f1)):
if f1[i] == f2[i]:
f3.append("True")
else:
f3.append("False")
print(f3)
Explanation:
This line defines the function
def match(f1,f2):
This line creates an empty list
f3 = []
This line is a loop that iterates through the lists f1 and f2
for i in range(0,len(f1)):
The following if statement checks if corresponding elements of both lists are the same
if f1[i] == f2[i]:
f3.append("True")
If otherwise, this is executed
else:
f3.append("False")
This prints the newly generated list
print(f3)
Write a function addUpSquaresAndCubes that adds up the squares and adds up the cubes of integers from 1 to N, where N is entered by the user. This function should return two values - the sum of the squares and the sum of the cubes. Use just one loop that generates the integers and accumulates the sum of squares and the sum of cubes. Then, write two separate functions sumOfSquares and sumOfCubes to calculate and return the sums of the squares and sum of the cubes using the explicit formula below.
Answer:
All functions were written in python
addUpSquaresAndCubes Function
def addUpSquaresAndCubes(N):
squares = 0
cubes = 0
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
return(squares, cubes)
sumOfSquares Function
def sumOfSquares(N):
squares = 0
for i in range(1, N+1):
squares = squares + i**2
return squares
sumOfCubes Function
def sumOfCubes(N):
cubes = 0
for i in range(1, N+1):
cubes = cubes + i**3
return cubes
Explanation:
Explaining the addUpSquaresAndCubes Function
This line defines the function
def addUpSquaresAndCubes(N):
The next two lines initializes squares and cubes to 0
squares = 0
cubes = 0
The following iteration adds up the squares and cubes from 1 to user input
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
This line returns the calculated squares and cubes
return(squares, cubes)
The functions sumOfSquares and sumOfCubes are extract of the addUpSquaresAndCubes.
Hence, the same explanation (above) applies to both functions

For an alternative to the String class, and so that you can change a String's contents, you can use_________ .
a. char.
b. StringHolder.
c. StringBuilder.
d. StringMerger.
Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.

Options:
The mailman would sometimes take a different path to deliver each letter to your home.
Letters would be written on the outside of envelopes for all to read instead of letters put inside envelopes.
Routers work in different ways and they take the fastest route no matter what is the direction they have to take, so they travel to several servers trying to find the fastest path to their destination, it changes almost everytime because of the use of servers and the conection speed of the different routes they can connect to, so that would be the option.

You've been hired by Maple Marvels to write a C++ console application that displays information about the number of leaves that fell in September, October, and November. Prompt for and get from the user three integer leaf counts, one for each month. If any value is less than zero, print an error message and do nothing else. The condition to test for negative values may be done with one compound condition. If all values are at least zero, calculate the total leaf drop, the average leaf drop per month, and the months with the highest and lowest drop counts. The conditions to test for high and low values may each be done with two compound conditions. Use formatted output manipulators (setw, left/right) to print the following rows:________.
September leaf drop
October leaf drop
November leaf drop
Total leaf drop
Average leaf drop per month
Month with highest leaf drop
Month with lowest leaf drop
And two columns:
A left-justified label.
A right-justified value.
Define constants for the number of months and column widths. Format all real numbers to three decimal places. The output should look like this for invalid and valid input:
Welcome to Maple Marvels
------------------------
Enter the leaf drop for September: 40
Enter the leaf drop for October: -100
Enter the leaf drop for November: 24
Error: all leaf counts must be at least zero.
End of Maple Marvels
Welcome to Maple Marvels
------------------------

Your program is going to compare the distinct salaries of two individuals for the last 5 years. If the salary for the two individual for a particular year is exactly the same, you should print an error and make the user enter both the salaries again for that year. (The condition is that there salaries should not be the exact same).Your program should accept from the user the salaries for each individual one year at a time. When the user is finished entering the salaries, the program should print which individual made the highest total salary over the 5 year period. This is the individual whose salary is the highest.You have to use arrays and loops in this assignment.In the sample output examples, what the user entered is shownin italics.Welcome to the winning card program.
Enter the salary individual 1 got in year 1>10000
Enter the salary individual 2 got in year 1 >50000
Enter the salary individual 1 got in year 2 >30000
Enter the salary individual 2 got in year 2 >50000
Enter the salary individual 1 got in year 3>35000
Enter the salary individual 2 got in year 3 >105000
Enter the salary individual 1 got in year 4>85000
Enter the salary individual 2 got in year 4 >68000
Enter the salary individual 1 got in year 5>75000
Enter the salary individual 2 got in year 5 >100000
Individual 2 has the highest salary
In python:
i = 1
lst1 = ([])
lst2 = ([])
while i <= 5:
person1 = int(input("Enter the salary individual 1 got in year {}".format(i)))
person2 = int(input("Enter the salary individual 1 got in year {}".format(i)))
lst1.append(person1)
lst2.append(person2)
i += 1
if sum(lst1) > sum(lst2):
print("Individual 1 has the highest salary")
else:
print("Individual 2 has the highest salary")
This works correctly if the two individuals do not end up with the same salary overall.
