Question

Using a MIPS program, you should define an array of 10 elements in your data segment with these values:
A = {11, 12, 10, 13, 9, 12, 14, 15, 20}
a. Write a function which finds the maximum value of this array.
b. Write another function which calculates the summation of this array.
c. Call these functions in your main program, and print the outputs of these functions to the user
i. “The maximum is 15”
ii. “The summation is 56”
d. What is the address that has been used by the simulator for this array?
