The first three problems in this Exercise refer to the following function, given in MIPS assembly. Unfortunately, the programmer of this function has fallen prey to the pitfall of assuming that MIPS is a word-addressed machine, but in fact MIPS is byte-addressed.

Note that in MIPS assembly the “;” character denotes that the remainder of the line is a comment.

Change this code to make it correct for 32-bit integers.
