Looking at first and third arguments, we can satisfy both by putting A =1 and B and C to 0 , now it can be easily checked that other constraints are still true.

Provide short answers to the following questions: A switching function is said to be neutral if the number of input combinations for which its value is 1 is equal to the number of input combinations for which its value is 0. Compute the number of neutral switching functions of $n$ variables (for a given n).
