6.31 [10] <§6.6> One extension of the MIPS instruction set architecture has two

new instructions called movn (move if not zero) and movz (move if zero). For example,

the instruction

     movn $8, $11, $4

copies the contents of register 11 into register 8, provided that the value in register

4 is nonzero (otherwise it does nothing). The movz instruction is similar but

copying takes place only if the register’s value is zero. Show how to use the new

instructions to put whichever is larger, register 8’s value or register 9’s value, into

register 10. If the values are equal, copy either into register 10. You may use register

1 as an extra register for temporary use. Do not use any conditional branches.
