MIN MAX XOR

$John$ is a computer science student and he is currently working on a project for his class. His professor gave him three binary strings $A$, $B$, and $C$ each of length $N$ and asked him to find a new string V, by following these steps: - Find the minimum bitwise XOR between $A$ and $B$, which creates a new string $D$. - Using string $D$, find the maximum bitwise XOR between $D$ and $C$.
