(Exercise) Mystery Figure out what number is being returned by mystery function by examining $v0 or printing it out using putDec as in this lab. Q3. What is the C equivalent code? Q4 What is printed as the result of mystery(7)? 5. What is printed as the result of mystery(32)? Now that you figured out the actual function of mystery, rewrite it so it obeys all the proper register conventions (Exercise) Mystery Figure out what number is being returned by mystery function by examining $v0 or printing it out using putDec as in this lab.
