Answer #1

addiu $t0, $zero, 8       #$t0 = 8
addi $t1, $t0, 1       #$t1 = 9
sw $t1, -4($t0)           #Mem[8-4] = 9 Mem[4] = 9
addi $t1, $t0, -4       #$t1 = (8-4) = 4
sw $t1, 4($t0)           #Mem[8+4] = 4 Mem[12] = 4

0x0:   unknown
0x4:   9
0x8:   unknown
0xC:   4
0x10:   unknown
0x14:   unknown
