3. Write and run the following MIPS code: .text .globl main main: add $t0,$0, $0 linel: addi $t0,$t0, 0xA move $a0,$t0 li $v0, 1 syscali li $v0, 10 syscall 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, 0xffffff 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
