$4.$ If $t$2$ has the base of the array A and $s$2$ corresponds to h$,$ the assignment statement A$[500]=$ h $-$ A$[500]$; is compiled into:

lw $t$0,1500($$t$2)$ # Temporary reg $t$0$ gets A$[500]$ sub $t$0,$$s$2,$$t$0$ # Temporary reg $t$0$ gets h $-$ A$[500]$ sw $t$0,1500($$t$2)$ # Stores h $+$ A$[500]$ back into A$[500]$

What is the MIPS machine language code for the above three instructions?
