This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

By next number, do you mean keeping x fixed, you want to search for the next such n?

Agnishom Chattopadhyay - 3 years, 5 months ago

I have edited the Problem a little bit.

Rishabh Deep Singh - 3 years, 5 months ago

@Rishabh Deep Singh – Well, for the bits where x has a 1, n can have anything, and for the places where x has a 0, n must have a 0 too. Does that answer your question?

@Agnishom Chattopadhyay – Can u write code for that ? to print all numbers Please?

Rishabh Deep Singh - 3 years, 5 months ago

@Rishabh Deep Singh – That's an interesting exercise. If you are stuck on this, I'd urge you to consider writing your code recursively. That might help. Or if you are not concerned about efficiency, you may loop over all the values and check if it satisfies the condition.

@Agnishom Chattopadhyay – Efficiency is More important, Can u help me with code?

I Found a Blog about it on Codeforces as SOS Dynamic Programming @Agnishom Chattopadhyay
