Design a circuit that has 4 inputs A, B, C, D and 4 outputs X, Y, Z, W.

 Hi please help me to solve this question it's from book "Fundamentals of Logic Design (7th Edition) ":

Design a circuit that has 4 inputs A, B, C, D and 4 outputs X, Y, Z, W. the input represent a Binary Coded Decimal (BCD) Number (0 to 9). XYZ output represent the Quotient and W represent the Remainder of a division of ABCD over "2". Assume invalid inputs do not occur (Don't cares) then realize the circuit using:

A-  ROM (Show Truth table, ROM block diagram, K-map for every output and the internal ROM realization)?

B-  Minimum 2-level NAND circuit? C- PLA (Table and Realization)?
