Consider the following MIPS assembly code:$$

$$lw $t$1,$ &a$$

$$lw $t$2,$ &b$$

$$mul $t$3,$ $t$1,$ $t$2$

L$1$:$$

$$bne $t$1,$ $t$2,$ L$2$

$$j exit$$

L$2$:$$

$$bgt $t$1,$ $t$2,$ L$3$

$$sub $t$2,$ $t$2,$ $t$1$

$$j L$1$

L$3$:$$

$$sub $t$1,$ $t$1,$ $t$2$

$$j L$1$

exit:$$

$$div $t$3,$ $t$3,$ $t$1$

$$sw $t$3,$ &c$$

Assuming initial values of a $=9$ and b $=15,$ what will be the value of c when the code completes its execution?$$
