sir i am facing a problem to map my inputs and outputs in the if condition that is in read input data bit for multiple pins kindly help me the same.

This sounds like the identical problem one of your class mates asked not too long ago.
Why not cheat together with him/her to leave less traces of the cheating for the teacher to locate?
