Build Full Adder from Halves | Dataford Interview Questions

Explain how to design a full adder using half adders.

Implement full_adder(a, b, carry_in) using two half-adder operations. Each input is a bit, represented by integer 0 or 1; return [sum_bit, carry_out], with both values also represented as 0 or 1.

Constraints

a, b, and carry_in are each either 0 or 1
Return exactly two values in the order [sum_bit, carry_out]
The implementation must compose two half-adder operations

Function Signature

def full_adder(a, b, carry_in):
