Write the fastest finger first program in memory model form to detect the earliest respondent for a quiz show. There are four participants for the quiz show. Their switch button input is connected at port address $40$h after converting it into an $8-$bit binary number. The bit $0,2,4$ and $6$ are assigned to the state of switches for participant $1,2,3$ and $4$ respectively. Hence, input values $01$h$,04$h$,10$h or $40$h indicate that participant $1,2,3$ or $4$ is the first one to press the switch button. In response, the corresponding buzzer makes a sound and also a led light begins to glow. At the same time other switches stop working and later responses from participants are ignored and no further buzzer is activated along with the led light. Buzzers and led lights are attached to the relays connected at port addresses $42$h$,52$h$,62$h and $72$h respectively. To restart the program, a switch connected at port address $50$h is to operate ON$.$
