Question

Write a MIPS assembly language program that will cover the following steps: Prompt the user to enter a first negative integer in the range [-30, 0) named integer1 Prompt the user to enter a second negative integer in the range [-20, -5] named integer2 Compute (int1 - 2*int2) // don’t use subi; If the result is a positive number, print a message saying “the result is a positive number equal to result_value” Else, if the result is a negative number, print a message saying “the result is a negative number equal to result_value” Repeat until sentinel value entered The program should enforce the rule that the two entered integers must be in the correct intervals. If the entered integer is not in the specified range, prompt again the user to enter an integer in the specified range. Use 99 for the sentinel value. It will allow the user to exit the program
