4.25 Four chairs are placed in a row:
BCD
Each chair may be occupied (1) or empty (0). Give the minterm and maxterm
expansion for each logic function described.
(a) F(A, B, C, D) is 1 iff there are no adjacent empty chairs.
(b) G(A, B, C, D) is 1 iff the chairs on the ends are both empty.
(c) H(A, B, C, D) is 1 iff at least three chairs are full.
(d) J(A, B, C, D) is 1 iff there are more people sitting in the left two chairs than in
the right two chairs.
