Design a Switch-Control Circuit | Dataford Interview Questions

You have an electric circuit with 2 switches, a voltage source, and a bulb. How would you design a circuit that will change the bulb mode no matter what switch you press?

Implement bulb_mode to model the behavior. Given the initial mode and a sequence of switch presses, return the bulb mode after every press. Each press is represented by 0 or 1, and either switch must toggle the bulb exactly once.

Function signature: bulb_mode(initial_mode, presses). Return a list of integer modes, where each mode is 0 or 1.

Constraints

initial_mode is either 0 or 1
0 <= len(presses) <= 1000
Each value in presses is either 0 or 1
Each press toggles the bulb exactly once

Function Signature

def bulb_mode(initial_mode, presses):
