(Using Matlab) Write a function to "smooth" a black-and-white image by replacing each pixel by the average of itself and its neighbors. In MATLAB a black-and-white image is just a matrix of 1s and 0s - 1 represents white, and 0 represents black.

To keep the algorithm simple, ignore the edges of the image - that is, do not change the first and last rows and columns.

function name = smooth_image()

input argument = input matrix

output argument = output matrix

The algorithm can be described as follows:

  • Given an NxM input matrix
  • make a copy of the matrix - this will be the output matrix
  • loop over rows 2 to N-1 of the input matrix
  • loop over columns 2 to M-1 of the input matrix
  • take the average of the 3x3 submatrix centered on the current row & column
  • set the corresponding element of the output matrix equal to this average

Problem 1: [10 Marks] Given a generic array with ‘n’ items (not only integers). Give a solution for checking whether there are any duplicate elements in the array or not? You just need to return a boolean (true or false). State the complexity of your solution. Can you come up with another solution that has O(n logn) complexity? Explain.

Problem 2: [10 Marks] Now consider the same problem as problem 1, but this time you only have positive integer numbers ranging from 0 to (n-1) in the array. Can you find a duplicate in O(n) complexity? Implement the solution.

From 1977 to 1982, Internet Engineering Notes (IENs) were used to document and generate discussion about various topics related to the Internet and Internet protocols. One of the challenges facing the early Internet was inconsistent data representation, including byte ordering. IEN 137 addresses this challenge. Note the date of the IEN, which suggests that it is meant to be at least somewhat whimsical, although still addressing an important topic in computer and network systems.

  1. What is the title of IEN 137?
  2. Who is the author of IEN 137?
  3. What is the title of the work of literature used to make several points in this IEN?

Problem 5: (10 pts) Modify the patient class with two overloaded methods to display a bill for astandard visit based on age. In the first method do not use any parameters to pass in data. If the patient is over 65, then a standard visit is $75. If the patient is under 65, then the standard doctors office visit is $125. Build a second method where you pass in a discount rate. If the patient is over 65, then apply the discount rate to a standard rate of $125. Create a main method that calls both of these methods and displays the results

Given an array A[0 … n-1], where each element of the array represent a vote in the election. Assume that each vote is given as an integer representing the ID of the chosen candidate. Can you determine who wins the election? What is the complexity of your solution? Hint: it is similar to finding the element that is repeated the maximum number of times.

C#

What to submit:

One zip file named Ass3.zip

This zip must contain one VS 2017 solution named Ass3, which contains one C# Windows Forms App project also named Ass3 and the project contains a default form, Form1.cs and Program.cs.

No change should be made in Program.cs, but your Form1 must be designed and implemented to satisfy the following requirements.

**Do not submit only a single file of the solution or project. The whole solution folder of VS 2017 must be zipped and submitted for grading.

Requirements:

  1. Use VS 2017 to create a C# Windows Forms App project whose solution and project are named Ass3. When all requirements below are finished and tested, zip the entire solution as Ass3.zip and upload it for grading.
  2. Use the same Functional Requirement as described in Assignment 2 with the changes below.
  3. Except the Form1 class given by Visual Studio, no other classes need to be defined. That is, the program you did in Assignment 2, including data and methods of the two classes should be "transplanted" in the Form1 class of this Ass3 project.
  4. All input and output should be done within Form1 and visual controls (e.g., textboxes, labels, buttons, etc.) on the form. That is, no console is used--no more command line I/O and no display in the Command Prompt.
  5. Specifically, the two initial integers and each guess should be entered in a corresponding textbox (i.e., three textboxes in total) and the error message "You must enter a number between ... and ...!" will be displayed by a label in red. A second label should be used to display in blue the hint "Higher...", "Lower...", and "You win!". Finally, let the ending message "----End of Game----" be displayed in the form title (in black since title color cannot be changed).
  6. Set the font size of all visual controls to be 18 points.
  7. Add a button showing 'Generate Secrete Number' to create a secrete number every time it is clicked. Because this button can be clicked at any time, there might be an error or hint displayed from the previous play, this button should also erase both labels to empty and reset the form title to 'Form1' when clicked.
  8. To accept a guess, a second button showing 'Guess' should be added on the form. Each time when it is clicked, it first erases the labels from their previous display and then show the error and/or hint message, depending on the guess entered.
  9. Place each visual control in Form1 so they look like the form shown in the demo program attached below.
  10. Same as in Assignment 2, we assume there are always two valid input integers entered to define the range of the random secrete number, and an integer is always entered as the guess value. That means there is no need to validate all three input integers except the guess value could still be out of the range, which explains (in item 5 above) why an error message needs to be displayed.
