3. Write and run the following MIPS code : .text .globl main main: add $t0,$0, $0 linel: addi $t0,$t0, OxA move $a0,$t0 li $v0, 1 syscall li $v0, 10 syscall What is the value of $t0, what is the output ? 4. Write and run the MIPS code in question 3 replacing linel: with: addi $t0,$t0, -20 What is the value of $t0, what is the output ? 5. Write and run the MIPS code in question 3 replacing linel: with : ori $t0,$t0, -20 What is the output message ? 6. Write and run the MIPS code in question 3 replacing linel: with : ori $t0,$t0, Oxffffff What is the output message ? 7. Write a MIPS program that computes the variable result using the following formula : result=x+x-y+z, where x=10, y=3 and z=1000
