Convert the following MIPS code into C/C++ functions int func() and int go() where $a0 and $a1 are the input integer parameters to the function a while a and b both pass their return values through $v0.

a: addi $sp, $sp, -12

sw $ra, 8($sp)

sw $s1, 4($sp)

sw $s0, 0($sp)

move $s0, $a0

move $s1, $a1

jal b

add $v0, $v0, $s0

lw $ra, 8($sp)

lw $s1, 4($sp)

lw $s0, 0($sp)

addi $sp, $sp, 12

jr $ra

g: mul $v0, $s0, $s1

jr $ra
