Question

IN MIPS ASSEMBLY LANGUAGE

Write an assembly program to read three 32-bit signed integers from the user. Determine the smallest of these three numbers and display this result. Don’t use loops. Prompt the user for each entered integer.

Your output should look something like the following example.

Enter an integer: 7556

Enter an integer: -22984

Enter an integer: 8875

-22984
