please please please make sure all the steps and work are written and please make sure it is right.

Using one appropriate-sized decoder and additional external gates (as necessary), design a full-adder whose inputs are A, B, and C_in, and outputs are Sum and C_out. You may use the block diagram of the decoder (there is no need to show the internal gates of the decoder). Clearly label all the inputs and outputs, and minterms. Draw a neat and clear diagram.
