# A tiny "Integrated" Logic Gate System
# Imagine 3 bits: A, B, C.
# Each bit's next state depends on the other two.

def integrated_system(state):
    A, B, C = state

    # Each node is a function of the WHOLE system
    new_A = 1 if (B + C) >= 1 else 0
    new_B = 1 if (A + C) == 1 else 0
    new_C = 1 if (A + B) != 1 else 0

    return (new_A, new_B, new_C)

# This has (very tiny) Phi because you cannot calculate 'new_A'
# without knowing the state of the 'whole' (B and C).
# If you "cut" the connection between B and A, the system's
# behavior changes fundamentally.
