this is what was in negator.circ

Build a 3-bit two's complement negator from only basic logic gates (OR, NOR, AND, NAND, NOT, XOR, XNOR). Your circuit should go in negator.circ. Your solution will involve a 3-bit ripple-carry adder. o To reduce duplication and effort, we suggest you build the 3-bit adder out of 3. multiple 1-bit adders. The 1-bit adder should be in a subcircuit called "adder1". o Notice that negator.circ includes a reference implementation to test yours against
