For any positive integer S, if we sum up the squares of the digits of S, we get another integer S1. If we repeat the process, we get another integer S2. We can repeat this process as many times as we want, but it has been proven that the integers generated in this way always eventually reach one of the 10 numbers 0, 1, 4, 16, 20, 37, 42, 58, 89, or 145. Particularly, a positive integer S is said to be happy if one of the integers generated this way is 1. For example, starting with 7 gives the sequence {7, 49, 97, 130, 10, 1}, so 7 is a happy number.
Your task is to write a function compute_happy_numbers(range1, range2) , where range1 and range2 are each tuples of the form (lower_bound, upper_bound), and returns a tuple containing: (1) the number of happy numbers in range1, (2) the number of happy numbers in range2, (3) the number of the range (1 or 2) containing more happy numbers, or None if both ranges have the same number of happy numbers.
def compute_happy_numbers(range1, range2):
"""Your code here"""
Test Cases:
compute_happy_numbers((1,1), (1,1)) (1, 1, None)
compute_happy_numbers((1, 10), (11, 100)) (3, 17, 2)

Indentation is very important in python. You need to indent code inside while loops, for loops, if statements, etc. You don't seem to be indenting.
In this example:
while (secretNum != userGuess):
userGuess = int(input("Guess a number between 1 and 20: "))
Although, you might need to indent more than only this line. I hope this helps.

Uyen decides to write a Python program to count towards the next birthday.
In order to do so, she plans to write a function count_days(start_date, end_date) which takes in the start date and end date in the string format, "dd/mm/yyyy", and returns the number of days between the start date and end date. The start date is included while the end date is not included in the count. Note that leading zeros in start_date and end_date are skipped if there are any (For example, the date 1st January 2017 will be in the format 1/1/2017).
Currently, Uyen has only completed a skeleton of count_days, and a few helper functions, which are provided below.
Your Tasks:
(a) Help Uyen complete the four functions marked with 'TODO'. They are get_day_month_year, less_than_equal, next_date and count_days.
(b) Uyen was quite careless, she didn't check for input data validity. You will also need to help her with this. We only proceed to count days if the dates are valid, and the start date is before or same as the end date.
Assume a valid date is between 1/1/1970 and 31/12/9999. The leap year and valid date check are already provided.
If one of the dates is not valid, throw an exception with a message that has the value: "Not a valid date: " + date, where date is the invalid date.
If the start date is after the end date, throw an exception with a message value: "Start date must be less than or equal end date."
Note: is_leap_year(year) and is_valid(d, m, y) are provided, you can make use of them.
Incomplete code:
def is_leap_year(year):
# DONE: do not need to modify
if year % 4 == 0 and year % 100 != 0:
return True
if year % 400 == 0:
return True
return False
def is_valid(d, m, y):
# DONE: do not need to modify
# d, m, y represents day, month, and year in integer.
if y < 1970 or y > 9999:
return False
if m < 1 or m > 12:
return False
if d < 1 or d > 31:
return False
if m == 4 or m == 6 or m == 9 or m == 11:

# return a tuple of integer (day, month, year).
return (d, m, y)
def count_days(start_date, end_date):
# date is represented as a string in format dd/mm/yyyy
start_day, start_mon, start_year = get_day_month_year(start_date)
end_day, end_mon, end_year = get_day_month_year(end_date)
# TODO: check for data validity here #
# if start date is not valid...
# if end date is not valid...

# lazy - let the computer count from start date to end date

count = count + 1
start_day, start_mon, start_year = next_date(start_day, start_mon, start_year)

next_date(31, 12, 2014) (1, 1, 2015)
next_date(30, 5, 2014) (31, 5, 2014)
To complete the function get_day_month_year(date), we can split the date string using the / character as a delimiter and return a tuple of integers:
def get_day_month_year(date):
day, month, year = date.split('/')
return (int(day), int(month), int(year))
To complete the function less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year), we can compare the year, month, and day of the start date to the year, month, and day of the end date and return True if the start date is less than or equal to the end date:
def less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):
if start_year < end_year:
return True
elif start_year == end_year:
if start_mon < end_mon:
return True
elif start_mon == end_mon:
if start_day <= end_day:
return True
return False
To complete the function next_date(d, m, y), we can first increment the day by 1 and check if the resulting date is valid. If it is not valid, we can set the day to 1 and increment the month by 1. We can continue this process until we reach a valid date:
def next_date(d, m, y):
d += 1
while not is_valid(d, m, y):
d = 1
m += 1
if m > 12:
m = 1
y += 1
return (d, m, y)
Finally, to complete the function count_days(start_date, end_date), we can add code to check the validity of the start and end dates, and throw an exception if either of them is not valid or if the start date is after the end date. We can do this by calling the is_valid function and the less_than_equal function:
def count_days(start_date, end_date):
start_day, start_mon, start_year = get_day_month_year(start_date)
end_day, end_mon, end_year = get_day_month_year(end_date)
if not is_valid(start_day, start_mon, start_year):
raise Exception("Not a valid date: " + start_date)
if not is_valid(end_day, end_mon, end_year):
raise Exception("Not a valid date: " + end_date)
if not less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):
raise Exception("Start date must be less than or equal end date.")
count = 0
while less_than_equal(start_day, start_mon, start_year, end_day, end_mon, end_year):
count = count + 1
start_day, start_mon, start_year = next_date(start_

To qualify for a particular scholarship, a student must have an overall grade point average of 3.0 or above and must have a science grade point average of over 3.2. Let overallGPA represent a student’s overall grade point average and let scienceGPA represent the student’s science grade point average. Which of the following expressions evaluates to true if the student is eligible for the scholarship and evaluates to false otherwise?
a: (overallGPA > 3.0) AND (scienceGPA ≥ 3.2)
b: (overallGPA > 3.0) AND (scienceGPA > 3.2)
c: (overallGPA ≥ 3.0) AND (scienceGPA ≥ 3.2)
d: (overallGPA ≥ 3.0) AND (scienceGPA > 3.2)
Answer:
([tex]overallGPA \ge 3.0[/tex]) AND ([tex]scienceGPA > 3.2[/tex])
Explanation:
Given
[tex]overallGPA \to[/tex] Overall Grade Point Average
[tex]scienceGPA \to[/tex] Science Grade Point Average
Required
The expression that represents the given scenario
From the question, we understand that:
[tex]overallGPA \ge 3.0[/tex] --- average [tex]greater\ than\ or[/tex] equal to [tex]3.0[/tex]
[tex]scienceGPA > 3.2[/tex] --- average [tex]over[/tex] 3.2
Since both conditions must be true, the statements will be joined with the AND operator;
So, we have:
([tex]overallGPA \ge 3.0[/tex]) AND ([tex]scienceGPA > 3.2[/tex])

{
if (col > 0)
{
if (arr[row][col] >= arr[row][col - 1])
{
System.out.println("Condition one");
}
}
if (arr[row][col] % 2 == 0)
{
System.out.println("Condition two");
}
}
}
As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
A. "Condition one" is printed twice, and "Condition two" is printed twice.
B. "Condition one" is printed twice, and "Condition two" is printed once.
C. "Condition one" is printed once, and "Condition two" is printed twice.
D. "Condition one" is printed once, and "Condition two" is printed once.
E. "Condition one" is never printed, and "Condition two" is printed once.
Answer:
C. "Condition one" is printed once, and "Condition two" is printed twice.
Explanation:
Given
The above code segment
Required
The number of times [tex]each\ print\ statement[/tex] is executed
For "Condition one" to be printed, the following conditions must be true:
if (col > 0) ---- the column must be greater than 0 i.e. column 1 and 2
if (arr[row][col] >= arr[row][col - 1]) --- the current element must be greater than the element in the previous column
Through the iteration of the array, the condition is met just once. When
[tex]row = 1[/tex] and [tex]col = 2[/tex]
[tex]arr[1][2] > arr[1][2-1][/tex]
[tex]arr[1][2] > arr[1][1][/tex]
[tex]4 > 3[/tex]
For "Condition two" to be printed, the following condition must be true:
if (arr[row][col] % 2 == 0) ----array element must be even
Through the iteration of the array, the condition is met twice. When
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
[tex]arr[0][1] = 2[/tex]

Explanation:
A, B & C form the vertices of a triangle.
∠ CAB = 90°, ∠ ABC = 73° and AB = 9.4.
Calculate the length of BC rounded to 3 SF
Question 1a
1. Create a (3,3) array where row 0 is [0, 0, 0], row 1 is [2, 2, 2], row 2 is [-2, -2, -2]. Print the array.
2. Change element [0,0] to 10 and element [2,2] to -10. Print the array.
3. Subtract 2 from every element. Print the array.
4. Print all of the elements of the revised array that are positive.

Question 1b
You are provided with two lists of numbers.
• List 'x' denotes all 8 possible dollar investment outcomes of a risky project;
• List 'p' denotes their corresponding outcome probabilities.
• For instance, there is a 5% chance of $10000.
In this question, let's first convert the two lists into two separate arrays. Can you use np.dot to calculate the expected value of this risky project? That is, 10000X0.05+1000X0.05+100X0.2 ... Calculation without using np.dot() will be considered no points.
Finally, print the following sentence using print+format: The expected value of this risky project is $XXX.X.

In [ ]: x = (10000, 1000, 100, 10, 1, 0, -10, -100]
p = [0.05, 0.05, 0.20, 0.20, 0.1, 0.1, 0.1, 0.2]
In [ ]: # Your code here
Answer:
(1) The program in Python is as follows:
rows, cols = (3, 3)
arr =[[0,0,0],[2,2,2],[-2,-2,-2]]
print(arr)
arr[0][0] = 10
arr[2][2] = -10
print(arr)
for i in range(rows):
for j in range(cols):
arr[i][j]-=2
print(arr)
for i in range(rows):
for j in range(cols):
if arr[i][j]< 0:
print(arr[i][j], end = ", ")
(2) The program in Python is as follows:
import numpy as np
x = [10000, 1000, 100, 10, 1, 0, -10, -100]
p = [0.05, 0.05, 0.20, 0.20, 0.1, 0.1, 0.1, 0.2]
q = np.dot(x,p)
print(q)
Explanation:
(1)
This initializes the rows and columns of the array to 3
rows, cols = (3, 3)
1. This creates and array and also populates it with the given data
arr =[[0,0,0],[2,2,2],[-2,-2,-2]]
Print the array
print(arr)
2. This changes index 0,0 to 10 and index 2,2 to -10
arr[0][0] = 10
arr[2][2] = -10
Print the array
print(arr)
This iterates through the rows and the columns of the array
for i in range(rows):
for j in range(cols):
3. This subtracts 2 from each array element
arr[i][j]-=2
Print the array
print(arr)
This iterates through the rows and the columns of the array
for i in range(rows):
for j in range(cols):
If array element is negative
if arr[i][j]< 0:
4. Print the array element
print(arr[i][j], end = ", ")
(2)
Line 1 and 2 are given as part of the program
x = [10000, 1000, 100, 10, 1, 0, -10, -100]
p = [0.05, 0.05, 0.20, 0.20, 0.1, 0.1, 0.1, 0.2]
This uses np dot to multiply x and p
q = np.dot(x,p)
This prints the result of the product
print(q)
