For this lab, you are going to write and test some assembly code using branches. You may want to watch first.

As with previous assignments, in order for your solution to work with my MUnit tests, you must follow these rules:

• The file name must be branches.asm.
• You must give your procedures the names indicated below.
• The procedures you write must be declared .globl.
• The method parameters will be placed in registers a0, a1, and a2. a0 will contain the first parameter, a1 the second, etc.
• Each method must end with the instruction jr $ra.
• Use the literal value 1 for true and 0 for false.

Problems

1. makes10(int a, int b) from CodingBat.
2. intMax(int a, int b, int c) from CodingBat.
3. close10(int a, int b) from CodingBat.
4. max1020(int a, int b) from CodingBat.
5. dateFashion(int you, int date) from CodingBat.
6. redTicket(int a, int b, int c) from CodingBat.

This GitHub Classroom repository has a file you can use as the starting point for your MUnit tests.

Submission and grading

Be sure to document and comment your code!

When your code passes all tests, commit your code with [Grade Me] in the message.

Hints:

• To compute !a0, do the following:
  not $a0, $a0
andi $a0, $a0, 1
  (The extra andi instruction makes sure that only the least-significant bit has a value other than 0.)
