Construct a 12-to-1-line multiplexer with a 3-to-8-line decoder, a 1-to-2-line decoder, and a 12x3 AND-OR. The selection codes 0000 through 1011 must be directly applied to the decoder inputs without added logic.

This is a 10-to-1-line multiplexer with a 3-to-8-line decoder, a 1-to-2-line decoder, and a 10x3 AND-OR and the selection codes 0000 through 1001 directly applied to the decoder inputs without added logic. Now how I can turn this into a 12-to-1-line multiplexer.
