Please answer part 4-6. Thanks!

Consider the following code for the following problems loop: LW R4, 0 (R3) ADDI R3, R3, 4 SUBI R1, R1, 1 Assume R3 points to the array with all 0 entries. R1 = R2 = 5. bl: # R0 is zero BEQ RO, R4, b2 ADDI R2, R2, 1 b2: BNE RO, R1, loop ADDI R3, R3, 4 Consider the following code for the following problems loop: LW R4, 0 (R3) ADDI R3, R3, 4 SUBI R1, R1, 1 Assume R3 points to the array with all 0 entries. R1 = R2 = 5. bl: # R0 is zero BEQ RO, R4, b2 ADDI R2, R2, 1 b2: BNE RO, R1, loop ADDI R3, R3, 4
