Add a copy constructor for the linked list implementation below:

Thank you for your time and help!

The following equation can be used to compute values of y as a function of x: ? = ?? −??sin(??)(0.012? 4 − 0.15? 3 + 0.075? 2 + 2.5?) where a and b are parameters. Write a Matlab script file (m file) with the following steps: Step 1: Define scalars a = 2, b = 5. Step 2: Define vector x holding values from 0 to π/2 in increments of Δx = π/40. Step 3: generate the vector y using element-wise product (dot product). Step 4. Compute the vector z = y 2 where each element holds the square of each element of y. Step 5: Combine x, y, and z into a matrix w, where each column holds one of the variables, and display w using the short g format. Step 6: Generate plots of y and z versus x using dashed lines. Step 7: Include legends for each plot (for y vs. x plot, use “y” as legend; for z vs. x plot, use “z” as legend).

Given the following numbers in the given order, show the red black tree

             100, 200, 150, 170, 165, 180, 220, 163, 164

Show the pre-order traversal of this red black tree while showing the color of each node in the pre-order traversal.

Write (C++) the red black tree code and insert the above numbers. Show the screen shot of the pre-order traversal of the resulting tree. Distinguish the colors by writing a * next to the black color values. Compare the result with the previous question.

Write a C-based language program in visual studio that uses an array of structs that stores student information including name, age, GPA as a float, and grade level as a string (e.g., “freshmen,”).

Write the same program in the same language without using structs.

(b) (5 pts) Show that any odd integer cubed is also an odd integer. Carefully show your algebra.

(c) (5 pts) Use your results from parts (a-c) in a direct proof to show that ”If a − b is even, then a 3 − b 3 is even.”

(5) (a) (2.5 pts) In your own words what is a base case and why is it important?

(b) (2.5 pts) In your own words what is an inductive hypothesis and how is it used?

(c) (10 pts) Prove that P(n) : 1+24+34+44+· · ·+n 4 = n 30 (n+1)(2n+1)(3n 2+3n−1), ∀n ≥

Case Project 3-3: Hardware Overheating The university is having some problems with the desktop computer that runs the Intel Core Duo CPU. The computers will suddenly scramble the display screens and freeze. Because of this, the university wants to stay away from having desktops running any of the Intel CPUs. What would you recommend to address the problem? Research some of the causes of overheating hardware and suggest possible remedies. In addition, what desktop CPUs would you recommend for replacing their older hardware? Provide an explanation for your recommendation and what the university should do in the future.

5. Write a program that prints all numbers between 27 and 78, one number per line.

6. In questions 6,7 the following list is used: [1,2,5,6,3,77,9,0,3,23,0.4,-12.4,-3.12]

7. Using “for” loop, write program that finds the smallest number in the list.

8. Using “for” loops, calculate arithmetic mean of all numbers in the list. Do not use built-in function in Python.

9. For this question envision you are creating a dummy alert to help the doctor determine if patient needs a mammogram or not: Ask the user to answer the following questions:

• "What is your patient’s gender? Please answer F for female, M for male " and store it in a variable "gender".

• "What is your patient’s age? " store it in a variable "age"

• "Does your patient have family history of breast cancer? Please answer with True or False " store it in a variable name "history" The program should display the following alert messages based on conditions:

• If patient is female and over 40 the system should alert the doctor to "consider ordering mammogram”

• If the patient is female but younger than 40 the program should go to next step and consider patient family history to determine if mammogram is recommended. If patient has family history of breast cancer the program should display a message "consider mammogram because of family history". If not just display "my not need mammogram" • In any other case the alert should say "no mammogram order recommended". Suggestion: Attention to the variable types when you input and compare.

Case Project 3-2: Desktop Computing The director has evaluated your server recommendations and asks you to design a strategy for upgrading the desktop hardware. He feels that most of the university’s desktop computers need to be replaced. You should explain your strategy.

Write a recursive a c++ code that checks if a number is Palindrome. A palindrome number is a number that reads the same from beginning to end and from end to beginning, in other words, a palindrome number remains the same when its digits are reversed. For example, 13431 is a palindrome number. 2332 is another one. (Note: Your algorithm should define and work with an integer number) The functionality of your code should be commented to explain what you do in each part of the code. You need to run your code for the following test cases and show the result:

1) 0 (output: yes)

2) 1234554321 (output: yes)

3) 123454321 (output: yes)

4) 1221 (output: yes)

5) 1234 (output: no)

6) 7676 (output: no)

7) -121 (output: yes)

8) -456 (output: no)

What is the time complexity of your algorithm? Cleary justify your answer.

Write a program in java to determine whether a given function F from the set {0,1,2,3,...,m} to (0,1,2,3,...,n} is one-to-one and/or onto. The inputs to your program will be:

- an integer m

- an integer n, and

- a two dimensional boolean array F of size (m+1) x (n+1), where F[ i , j ] = 1 if F(i) = j.

You are required to implement a Patient Information System for a clinic according to the following specifications:

• Class #1 PatientRecords (Tester class with main):

This class contains a full list of patients (array list) and it provides the following functionalities:

• Add patient by ID-Number

• Print all records

• Print the number of patients based on specific attributes such as: disease name, gender.

***** See examples below for the input format (use console)

• Class #2 Patient:

This class contains personal information about each patient. It consists of the following fields (private):

• Patient’s name

• Patient’s age

• Patient’s gender

• Patient’s date of last visit

• Patient’s disease and syndromes.

• Patient’s status (waiting-for-analysis-results, on-medication, healed)
  
  The class should provide a printRecord method for each patient.

• Class #3 Disease:

This class describes the basic information of a disease. It consists of the following fields:

• Disease’s name

• Array List of syndromes (such as fever, general weakness, …)

Examples of commands:

• add ID-Number                          ex:add 89548856
  This command adds a new patient with ID = 89548856 to the record. (If the ID is already in the list, print an error message).

• SetInfo ID-Number name, gender, age           ex:setInfo 89548856 “Ali”, “male”, 35

• Set ID-Number attribute value                      ex:set 89548856 date “16/10/2020"
                                                                          set 89548856 disease “flu”                                                                         set 89548856 status “healed”

• Adds ID-Number value                                ex:adds 89548856 “fever”
  -- Adds means add syndrome

• Print-record ID-Number                              ex:print-record 89548856

• This command prints the full details of the patient (in a clear format of your choice).

• Print-all

This command prints a table of all patients in the list (names, age and date of last visit)

• Print-all attribute value   ex:print-all gender “male”
  This command prints the count of all male patients in the list

print-all disease “flu”
Print-all status “on-medication”

General Notes:

• All commands are case insensitive.

• You are responsible for building a user-friendly console application (error messages, clear menu, input validation, ...)

• Use any suitable and useful OOP techniques (composition, enum, inheritance, ...)
