by using the generar of the match capansion 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.
