Consider the Scheme function merge-cards which consumes two card structures (cl and c2) and produces a new card, according to the following rules: . If the suits of the two cards are the same, the new card has that suit and its value is the sum of the values of cl and c2, up to a maximum value of 10 • Otherwise, the new card has the value of cl and the suit of c2. b) 12 marks Write the contract of merce-cards (the function header is given below). c) 12 marks Write a single example for merge-cards. d) 16 marks Complete the body of the function merge-cards.

Learning Objectives

After successfully completing this assignment, students will be able to:

Configure, run, and test a linux server in AWS' EC2
Configure, run, and test a Windows server in AWS' EC2

Requirements

Create an Ubuntu 20 LAMP server in EC2 like we did in class.
Verify your that Apache was installed by opening your browser and enter the public dns of your server in the address bar. If it does not connect either you did not add HTTP to the Security Group, or the install did not work properly. Take a screenshot and save it (for submission below).
The default location of html and php files is /var/www/html. Change to that directory. Now, using your favorite text editor use sudo to run your editor and create a file in that directory named info.php. For example, sudo nano info.php Then enter the following in that file to show information about the PHP installation: <?php phpinfo(); ?> Save the changes to the file and exit the editor.
Now in your browser, enter the public dns of your server in the address bar / info.php. For example, my public dns was ec2-54-89-230-235.compute-1.amazonaws.com, so I enter as the url. Take a screenshot and save it (for submission below).
Create a Windows 2016 Server, like we did in class.
Login to it using Remote Desktop. Take a screenshot of Remote Desktop connected to your Windows Server and save it (for submission below).

Clean Up

Now that you have completed the assignment, stop or terminate your EC2 instances. Stopping them means that it is now longer running, but your data is saved. That means you will not accrue charges on your running server. Terminating will both stop and delete the instances (also not accruing charges).

What to Submit

Screenshot of Apache page on your server shown in your browser
Screenshot of the PHP info page on your server shown in your browser
Screenshot of Remote Desktop session to your Windows Server

Question 4. [4 MARKS] You decide to save all your passwords in files, one password per file. You then decide you want to update your 6-character UTORid password, but you don't remember which of your password files you saved it in. Luckily, this is the only 6-character password you have so you decide to write a function to find the password and change it. Your code runs, but the function's body contains four bugs which will result in the function execution not matching its docstring description. In the space provided, rewrite the buggy lines with the bugs fixed. Do not add or remove any lines. def change password(files_list, new-password): " (list of str, str) -> str Preconditions: (1) files list is not empty. (2) Each file in files_list contains one single-line password. (3) All files in files_list contain passwords of different lengths. (4) Your 6-character password is guaranteed to be in one of these files. In the appropriate file from files_list, replace your 6-character password with new-password, and return your old password. #Code If you think a given line contains a bug, rewrite it. Otherwise leave it blank. found = True for filename in files list[:-1]: passwd_file = open(filename, 'r') first line = passwd_file.read() password = first line.strip("2") if password == 6: passwd_file.close() passwd_file = open(filename, 'w') passwd_file.write(new_password) found = True passwd_file.close() if found: # This is correct. Do not modify. return password
