Write a machine code program for all the following problems. Test to make sure that they work in LC3. It's best to complete each

step and test before moving onto the next. No credit if you write code in assembly. Your machine code file name must be named, Multiply.bin a. The LC-3 has no multiply instruction. You must write code to allow for multiplication of two numbers. These numbers must be loaded into the registers R3 and R4 from memory. Load R3 with contents of memory from x4000 and R4 from x4001. In other words, someone running this code will place the data in these two memory locations b. Write machine code to multiply the contents of R3 with the contents of R4. The result must be stored in R5. In other words, R5 R3 R4 c. You must also store the result at memory location x4002. d. Modify your code to change the contents of register R1 based on the final result stored in R5. i. If R5 is greater than 0, R1 must be set to 1 ii. If R5 is less than 0, R1 must be set to -1 iii. If R5 is equal to 0, R1 must be set to 0 1. Start your program at x3000 so that it will be easier for me to grade it. 2. Each program must include a header comment that has your name(s) and a brief description of the program 3. Make sure to comment logic of your program. You will be graded on comments.

Consider the following recursive method, which is intended to return a String with any consecutive duplicate characters removed.
saul85 [17]

Answer:

D. return str.substring(0, 1) + removeDupChars(str.substring(1));

Explanation:

The logic here is following:

If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.

If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.

When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.

Explain what the problems with the implementation of the function are, and show a way to fix them.// return true if two C string
Nataly [62]

Answer:

The code is not dereferencing the pointers. You have to place an asterisk in front of the pointer to read the value the pointer points to.

Explanation:

So "if (str1 != str2)" must be "if (*str1 != *str2)".

likewise:

   while (*str1 != 0 && *str2 != 0)

and

     result = (*str1 == *str2);
