PLEASE USE MIPS ASSEMBLY LANGUAGE

Assignment 2 Write a program in assembly language that asks the user to input two integers in the range 1 to 1,000 and calculates their product. You can only use shift, add or sub instructions to calculate the multiplication (not the mult instruction). The program should verify that both integers are within the specified range. If either on the integers are outside this range, the program should display a message "input range error" and ask the user to input again. If user persist in entering the wrong integers more than two times, the program should exit and display message "error limit exceeded." Else it should exit after calculating the product of the two integers that are within the specified range.
