Assume that two sensors are connected to P$3\mathrm{.}4$ and P$3\mathrm{.}5$ of the c onnected to P$3\mathrm{.}4$ is placed near $8051$ Microcontroller. Sensor entry door of the auditorium and another sensor is connected to P$3\mathrm{.}5$ is placed near the exit door. The maximum capacity of the auditorium is $200.$ Write an ALP to find the number of people inside the auditorium and send the count to port P$0.$ An LED connected to P$1\mathrm{.}7$ will glow if the auditorium is full.
