4. (40 pts) 7. Branch and Jump Instructions Given below is a MIPS assembly language function labeled FNC1. The address of each instruction is specified to the left in hexadecimal. The arguments passed to this function are $a0 and $a1.

0x00001000 FNC1: lb $t0, 0($a0)
0x00001004 sb $t0, 0($a1)
0x00001008 beq $t0, $zero, End
0x0000100C addi $a0, $a0, 1
0x00001010 addi $a1, $a1, 1
0x00001014 j FNC1
0x00001018 End: nop
