Pergunta de entrevista da empresa Texas Instruments

You are given two Full Adders (FA) and one Half Adder (HA). Using only these components, design a 3-bit adder that adds three single-bit inputs: A, B, and C. Your circuit should output a Sum and a Carry-out. Describe your logic design approach. You may assume all gates within the adders are ideal. Do not use any additional gates beyond the given components.
