Can you help me understand this Python question?

Question 1

You python code will simulate a slot machine: it will generate a ticket of 3 random numbers. You need generate 1000 tickets. These 3 numbers must range from 1-9. When these three numbers are all 7s, or 9s, you win this game. Every time you won, print out ‘Bingo! You won!’

You must print out each ticket, then count how many times you had won, and print how many times you won at the end of the program.

Example output:

3 6 9

8 9 4

7 7 7

Bingo! You won!

8 9 5

9 9 9

Bingo! You won!

3 9 7

2 9 6

You won 2 times!

Question 2.

This question will focus on String manipulation.

We will have a default string like: A_Beautiful_Rose_Is_Blooming_In_The_Garden.

Each word is separated by a underscore char “_”.

You need to do following steps:

2.1 (5 pts) Split the sentence by unserscore “_”, and store them in a word list, print out that list

2.2 (5 pts) Change all letters of 1^st word to upper case, the rest of the words all to lower case, then print the word list out

2.3 (5 pts) Join the word list back to a string using character “*”, print it out

2.4 (5 pts) Replace the word “rose” with your own favorite flower, daisy, gardenia, lily, tulip.

2.5 (5 pts) Reverse the new sentence and print them out

Sample output:

Please type a sentence: A_Beautiful_Rose_Is_Blooming_In_The_Garden.

2.1 output: [‘A’, ‘Beautiful’, ‘Rose’, ‘Is’, ‘Blooming’, ‘In’, ‘The’, ‘Garden.’]

2.2 output: [‘A’, ‘beautiful’, ‘rose’, ‘is’, ‘blooming’, ‘in’, ‘the’, ‘garden.’]

2.3 output: A*beautiful*rose*is*blooming*in*the*garden.

2.4 output: A*beautiful*tulip*is*blooming*in*the*garden.

2.5 output: .nedrag*eht*ni*gnimoolb*si*pilut*lufituaeb*A

Question 3.

Return the sum of the numbers in the array that are between 6 and 7. The first 6 should be excluded, and all 7’s should be excluded). Any number inside a 6 and 7 must be added to you sum, numbers outside of 6 and 7 should not be added.

Return 0 for no numbers.

Example output:

Sum67([])→ 0

sum67([1, 2, 2]) → 0

sum67([1, 6, 6, 10]) → 16

sum67([1, 6, 6, 10, 7]) → 16

sum67([1, 6, 6, 10, 7, 8, 7, 6, 1, 7, 7]) → 17

sum67([1, 1, 6, 7, 2]) → 0

Question 4.

This question focuses on Dictionary. We want to create a Dictionary to simulate the Hotel Booking list.

BookingNumber (int), Guest(String, firstname, lastname), RoomType(String, “suit”,“standard”), Price(Float), Date(String, “7/2-7/5”)

1. Create an empty BookingDict Dictionary, it must be a global variable. (in main function)
2. Define a function call createBooking(BookingNumber, Guest, RoomType, Price, Date). This function will add a new item to your BookingDict, with a Booking number that is an integer, and keeps increasing with each new book added.
3. Define a function call sortBooking(). In this function, you will sort your Dictionary first based on the guest then by the Price.
4. Call your createBooking function 5 Times to generate a BookingDict of 5 bookings. Display these five bookings.
5. Call your sortBy functions to sort the BookingDict, then print out the sorted bookings.

Question 5.

Max Subarray Sum: Given an array of integers, find the subarray which contains max sum.

For example,

Input: Given integer array :”1, 2, 4, -6, 3, 4, -1, 9″,

Output: “16”

Input: Given integer array :”1, 2, 4, -9, 3, 4, -1, 9″,

Output: “15”

Input: Given integer array :”1, 2, 4, -6, 3, 4, -6, 5″,

Output: “7”

Input: Given integer array :”1, 2, 4, -6, 3, 4, -8, 9″,

Output: “9”

Divide and Conquer:

There are three key words:

1. Find all subarrays
2. Find the sum of this subarray
3. Find the max sum and print it out

1.Review the prompt and draw your diagram in MySQL.

Design an E/R diagram for a bank, including information about customers and their accounts. For the customers, keep the following information: name, address, phone, and social security number. For accounts, keep the following information: account number, type (saving, checking), and balance. Your diagram should show the ownership relation between a customer and an account. You should also show all primary keys in your diagram. When using the MySQL model, you can assume any appropriate datatype for each column.

2. Review the prompt and draw your diagram in MySQL.

Change your diagram in the previous question (#1) so that a customer can have a set of addresses that are street-city-state and a set of phones. You are not allowed to use nonprimitive datatype such as a set value. Therefore, you should add other entity sets appropriate for the new conditions. Please also show all primary keys for all entities and relationships (e.g. one-many).

3. Review the prompt and draw your diagram in MySQL.

Design a database for the university registrar. This database should include information about students, departments, professors, courses, which students are enrolled in which courses, which professor are teaching which courses, student grades, TA’s for a course (TA’s are students), which courses a department offers, and any other information you think is appropriate. In addition, consider the following assumptions in your design:

• Each professor only works in one department.
• A course has at most one TA.
• A course is only taught by one professor and offered by one department.
• Students and professors have been assigned unique email ids.
• A course is uniquely identified by the course number, section number, and semester (e.g. cs220-1 spring 21).

You should also identify all the primary keys and relation types (e.g. one-many).

4. Consider the previous question (#3). Draw its UML diagram. You do not use MySQL for this question.

5. Review the prompt and draw your diagrams in MySQL.

Draw E/R diagrams for the following cases considering weak entity sets. In each case, indicate primary keys.

1. For entity sets courses and departments, suppose that a unique department gives a course, but its only attribute is its number. Different departments can offer courses with the same number. Each department has a unique name.
2. Consider entity sets leagues, teams, and players. League names are unique. No league has two teams with the same name. No team has two players with the same number. However, there can be players with the same numbers on different teams, and there can be teams with the same name in different leagues.

Challenge 5b – Comparing Sorting Algorithms

1.)  Use the attached skeleton  (I will put in comments the Zip file) and the attached PowerPoint (see below)

to write the driver class that has 3 methods that will accept an array of ints to sort using each of these algorithms:  insertion, selection, & bubble.  Note:  Make sure the sorting is in ASCENDING order!
 

2.)  Write a driver that will do the following:

a.)   Create an array of 20,000 ints (generate the numbers randomly in a loop, in the range of 1 – 5000)

b.)   Call each of the sorting methods, passing it the array of 20,000 ints (Note:  make a copy of the array before sorting the copy).

c.)   Calculate the number of nanoseconds taken to sort the same array, using each of the 3 algorithms.

d.)    Display the time for each.  Say which of the 3 algorithms was fastest (most efficient).

Hint #1: To prove that the algorithm is working, create a small array of 10 randomly generated ints between 1 and 100, and sort them using each of the 3 sorting methods, and print them after each sort. Make a copy of the original array, so that you are re-sorting an unsorted array, instead of the sorted array.  This is proof of concept.

Hint #2:  Make a copy of the original array, so that you use the unsorted version as input to each method.

Hint #3:  Use either System.currentTimeMillis() or System.nanoTime() to get the start and end time assigned to 2 long variables, then subtract, and that is your total time.

Extra Credit:  Do the same for mergeSort and quickSort.

Per the syllabus Requirements:

Assignments:

Each week, students will be assigned a CHALLENGE program, which will be started during the lab time, and must be completed and turned in via Canvas by midnight on Sunday. All programming assignments are required to be turned in as “zipped” Netbeans projects, so that the graders can have a consistent means of “unzipping” and testing the programs. 

Ensure your student id, section, and due date appear in the comments of your programming assignments, to give you proper credit. Do not put your name in the comments, since we use anonymous grading.

Thread activity

• Write a program that uses 5 threads. Initialize a shared variable with a value of 100.
• Each thread must add its Thread ID (tid) to the shared variable.
• Once a thread has done the addition, print the ID of the thread.
• It is important to make use of mutexes so that only one thread is incrementing the shared variable at a time.
• Output the value of the shared variable once all threads have finished incrementing it.
