ANSWER :

GIVEN

CODE:

li $t1, 10
sll $t2, $t0, 2           #offset for i
add $t3, $s0, $t2       #address of MemArray[i]
bgt $t0,$t1,IF_CON       #condition
ELSE:                   #else body
   lw $t4,0($t3)
   sub $t4, $0, $t4   #changing sign
   sw $t4,0($t3)
   j NEXT
IF_CON:                   #if body
   li $t4,0
   sw $t4,0($t3)       #storing zero
NEXT:
