Given the following combinational circuit, Determine the outputs functions A and $B$ as sums of minterms:

$A={\displaystyle \underset{?}{\overset{?}{}}}(1,2,4,7),B={\displaystyle \underset{?}{\overset{?}{}}}(3,5,6,7)$

$A={\displaystyle \underset{?}{\overset{?}{}}}(1,3,4,7),B={\displaystyle \underset{?}{\overset{?}{}}}(0,3,6,7)$

$A={\displaystyle \underset{?}{\overset{?}{}}}(1,3,4,7),B={\displaystyle \underset{?}{\overset{?}{}}}(3,4,6,7)$
