Must-Know Greedy Problem for Interviews-Simple Bulb Problem|Swift

In this video, we solve a very interesting bulb switching problem using a simple greedy trick.
You are given a row of bulbs where each switch not only toggles the current bulb but also flips all the bulbs to the right.
The goal is to find the minimum number of switches required to turn ON all the bulbs.
At first glance, this problem looks like it needs simulation or brute force.
But with a simple observation, we can solve it in O(N) time using a greedy approach.
In this video, you’ll learn:
How the bulb switching problem works
Why brute force is inefficient
