Design a logic circuit to convert a single digit BCD number to the number modulo six as follows (Do not detect illegal input):

(A)

Write the truth table for all bits. Label the input bits $I_1, I_2, \ldots$ with $I_1$ as the least significant bit. Label the output bits $R_1, R_2\ldots$ with $R_1$ as the least significant bit. Use $1$ to signify truth.

(B)

Draw one circuit for each output bit using, altogether, two two-input AND gates, one two-input OR gate and two NOT gates.
