Consider the figure in Exercise $3.$ If the current machine code that executes is $0214bfffd$ and the values of the registers in the processor are as shown below, what is then the value of the input WD$3?$ Answer as a $32-$bit hexadecimal value.

$$at=0x00011021$

$$v0=0x5234f1a0$

$$v1=01114f111$

$$a0=0xff001231$

$$a1=0xffffffff$

$$a2=0x32252341$

$$a3=0xff1245ee$

$$t0=0xffff12ff$

$$t1=0xffffffff$

$$t2=0xfffffff5$

$$t3=0xfffff67f$

$$t4=0x0121ffff$

$$t5=055f7fff5$

Assume that all other registers in the register file have value $0.$ answer question $4$ and Show explanation please
