Given the mapping of registers to variables below, write a program to implement the following expression:

Registers Variables

$t$0$ A

$t$1$ B

$t$2$ C

$t$3$ D

$t$4$ Z

Ex: If the values of $t$0,$ $t$1,$ $t$2,$ and $t$3$ are initialized in the simulator as:

Registers Data

$t$02$

$t$14$

$t$26$

$t$35$

the result is stored in $t$4$:

Registers Data

$t$02$

$t$14$

$t$26$

$t$35$

$t$47$

Note: Use the $\text{'}+\text{'}$ button under the Registers display to initialize register values for $t$0,$ $t$1,$ $t$2,$ and $t$3..$
