1. Translate the following code into MIPS
code.
B[i + 10] = B[i -2] + 40;
i = i + 10;
B[3] = B[i - 1];
a) Assume B is an array of integers (each integer takes 4
bytes). B's address
is stored at register $10. Also assume that the compiler associates
the
variable i to the register $11.
b) Assume B is an array of characters (each character takes one
byte). B's address
is stored at register $10. Also assume that the compiler associates
the variable i to the register $11.
2. Translate the following code into MIPS
code.
B [0] = 5;
for (i = 1 ; i < 50 ; i = i + 2)
{
B[i] =i + B[i-1];
}
Assume the compiler associates the variable i to the register
$t0. Also, assume B is an array of integers and its address is
stored at register $s1.
3. Translate the following code into MIPS
code.
for (i=0; i<=5; i=i+1)
{
if (i != k)
k=(k *2)-1;
else
k=(k *4)+1;
}
Assume the compiler associates the variables i and k to the registers $s0 and $s1, respectively.
4. Translate the following code into MIPS code.
Test (int i, int j)
{
int k;
k = Double(i+1) + Double (j-10)
return k;
}
Sub (int m)
{
int g;
g = m + m;
return g;
}
Assume the compiler associates the variable k to the register $s0. Assume the compiler associates the variable g to the register $t0.

Create a JavaScript program that asks for the input of at least five words (a total of 25+ characters) string from a user and performs the following functions to it:
STRING METHODS
Example: Input 5 words
Note: This is an example with example input. Your input will make this much different so don't hard code my examples into your code. The program should ask for input for the 5 words.
Enters: I think therefore I am
Check to make sure it is 25 characters in length. (step 1) - it is not, it is only 22 characters so have them try again.
Enters: Failure is success in progress (this is over 25 characters)
Output: Failure is success in progress (step 2)
Output in lowercase: failure is success in progress (step 3)
Output in uppercase: FAILURE IS SUCCESS IN PROGRESS (step 4)
Output character count: Your string has 30 characters. (step 5)
Output characters between index 5 and 10. re is (step 6)
Output 5 characters starting from position 15. ess i (step 7)
Combine with a 25+ character string you have created: Failure is success in progress Success is dependent on effort (step 8)
ARRAY METHODS - Working with the same string as the String Methods program, continue your program by completing these steps.
Example continued: Array Methods
Your list should be output of all words in your combined string: (step 1)
failure

The multi-merge sort algorithm (M&M sort) works like merge sort, except that instead of dividing the array into 2 partitions, it divides the array into p partitions. It recursively sorts each of the p partitions and then merges the results doing a p-way merge (except, of course, for the base case of a singleton or empty array). (a) Write the recurrence for T(n) for M&M sort for the case where p is a constant. Then, give a closed-form solution to the recurrence using the Master Theorem, and note which case applied. (b) Now assume that p is not a constant, but rather p(n) = n/10. Rewrite T(n) for this case. Then, give a closed form solution. Use the Master Theorem if it applies, or any other means of arriving at the result.

Lab – Linux Fundamentals Instructions: Using Kali Linux, the Windows Linux Sub-System, or another Debian based Linux distribution, perform the following tasks based on the Linux Fundamentals lecture. For this lab, take screenshots for all major steps completed to illustrate that each task was successfully completed (the same method as would be used for other labs).
9. Display your current directory in the terminal
10. Display your current directories contents including the inode value and permissions for each file and directory
11. Without using an editor, create a file with no contents called billy_bobs_diary.txt in the user BillyBob’s home directory
12. Edit your file using nano or vi and add the following string into the contents of the file: “This is my super-duper secret diary. No one shall read my diary for as long as I live. I will encrypt this with the moistest strongest encryption that is known to man. P.S. I really love kitten memes”
13. Rename the file to secret_file.txt using the command line
14. Move the file, secret_file.txt, to a directory named secret located in /opt
15. Create a copy of the file, secret_file.txt, and place it in BillyBob’s home directory
16. On the file, secret_file.txt, located in /opt/secret, change the file permissions so that all users have read/write access, but not execute
17. After you get weirded out that your professor just did that for fun, change the permissions so that the owning user has r/w, the owning group has r/w, and all other users have read only access
18. Display the contents of secret_file.txt via the command line without using a text editor
19. Append the following line to the document without using a text editor: “I have hidden this file so cleverly, that no one will ever find it. My secrets are safe here.”
20. Using the command line, clone the GitHub repository below into the /opt directory. Use the ReadMe to introduce yourself to the mystery scenario. After familiar with the scenario and the instructions, solve the mystery and take snapshots along the way, especially when you figure out who done it!

1. Obtain the following string: abcdefghijklmnopqrstuvwxyz (as input or using initialization)
2. Using recursion, write a reverse function that reverses the characters in a string or character array given two indices (starting and ending). The string or the character array should reflect the reversal.
3. Read indices as input 11,18 (i.e. letters 12,19)
4. Call the reverse function to reverse letters: 12-19
5. Read indices as input 4,22 (i.e. letters 5,23)
6. Call the reverse function to reverse letters: 5,23
7. Using the reverse function, reverse the alphabet 8. Print the reversed string or character array.
Your output should contain:
abcdefghijksrqponmltuvwxyz
abcdwvutsrqponmlkjihgfexyz
zyxwvutsrqponmlkjihgfedcba
NOTE: your recursive function should modify the original string passed in as an argument, NOT make additional copies of the original string

Assume a 32-bit system, with a 2-level page table, with a page size of 4KiB (p1=10bits, p2=10bits, offset=12bits).
(i) A program on this system requires 16MiB in total: the program text segment uses 4MiB, the program data requires 2MiB, the program dynamically allocates 8MiB on the heap, and the stack utilises 2MiB. How many page-table pages are required for this process? (Don’t answer with just a number, explain your reasoning. Without your reasoning we cannot award part marks if your answer is incorrect.)
(ii) Describe the lookup steps within the page tables to find the physical address of the logical address 0x00403004.
(iii) If the reference time to access the physical memory frame
is 20 nanoseconds. Assume that all required pages are in memory.
How long does a paged memory reference take, if—
i. There is no TLB?
ii. There is a TLB, with an access speed of 0.05 nanoseconds, but
the TLB does not contain information on the required page?
iii. There is a TLB, with an access speed of 0.05 nanoseconds, and
the TLB contains information on this page?
Do not answer with just a number, explain your reasoning.

In this programming assignment, you need to create 3 files.
1. DateType.h
2. DateType.cpp
3. A test driver for testing the class defined in the other 2 files. You can name your file in the way you like. Remember it must be a .cpp file.
In DateType.h file, type these lines:
// To declare a class for the Date ADT // This is the header file DateType.h
class DateType
{
public:
void Initialize(int newMonth, int newDay, int newYear); int
GetYear() const;
int GetMonth() const;
int GetDay() const;
private:
int year;
int month;
int day; };
// Class implementation // DateType.cpp
#include "DateType.h"
void DateType::Initialize(int newMonth, int newDay, int newYear)
{
year = newYear;
month = newMonth;
day = newDay; }
int DateType::GetMonth() const
{
return month;
}
In DateType.cpp file, type these lines:
int DateType::GetDay() const
{
return day;
}
int DateType::GetYear() const
{
return year; }
In you test driver, type in these lines:
// test driver
// I give the file name: testDriver.cpp
// To compile, type c++ DataType.cpp testDriver.cpp, this will
generate an a.out executable.
// Or, type c++ Type.cpp testDriver.cpp –o testdriver, this will
generate an executable named testdriver.
#include "DateType.h" #include <iostream>
using namespace std;
int main()
{
DateType today;
DateType anotherDay; today.Initialize(9, 24, 2003); anotherDay.Initialize(9, 25, 2003);
cout << "Today is " << today.GetMonth() << "/" << today.GetDay() << "/" << today.GetYear() << endl;
cout << "Anotherday is " << anotherDay.GetMonth() << "/" << anotherDay.GetDay() << "/" << anotherDay.GetYear() << endl;
return 0; }
Once you have the 3 files ready, you can compile them. The compile command is in the comments of the test driver.
After the compilation, you run the program, and see what output
you get.
Now, modify the code to initialize 2 different dates, compile and
run it, and see what the output is.

Using Perl;
Part 1:
Allow the user to enter a full name in the “first last”
format
Print just the first name
Print just the last name
Print the name in “last, first” format
Print the entire name out in all capital letters
Use a single print statement to print out the first name on one
line and the last name on
the next line.
There should be 5 print statements generating 6 lines of
output.
Part 2:
Enter a three digit number (such as 316)
Print out the number from the hundreds place (for example, 3 in
316)
Print out the number from the ten’s place (for example, 1 in
316)
Print out the number from the one’s place (for example, 6 in
316)
Print out the original number
All output will be appropriately labeled and on a separate line,
such as “hundreds
place”, “tens place”, and so on.
ALL the numeric values MUST be right justified in the output using
formatted output
All work done for this part MUST treat the information as numeric
values – do not treat
the input as a string or as an array.
There should be 4 print statements generating 4 lines of
output.
