You will develop RISC$-$V assembly language implementations of the following problem and print the results to ensure that both the C implementation and your RISC$-$V implementation compute the correct answer.

Your executables must be named as follows, and must be compiled with a Makefile

We will test your projects using autograder

Note that in all your programs below you must follow the RISC$-$V function calling conventions that we cover in class.

Your solutions must follow the logic and implement the same functions as given in the C code.

Remeber to remove the line # YOUR CODE HERE from the starter code.
