[Help] CSES problem set: Josephus Queries (Mathematics Section)
By prcsamrat, history, 8 months ago, In English

Hello, I am trying to solve the Josephus Queries (Mathematics section) problem, and I am not able to code the logic that is iterative and not recursive.

I am really trying hard to get through this problem, I just completed the introduction and graph sections.

Looking forward to help.

Thanks in advance.

Why does it have to be iterative? A recursive solution is probably easier to implement

I find recursive solution difficult to understand.

ordered_set is a cheatcode if u really wanna solve it

    Can you elaborate a bit more on this? I tried thinking in this way but not able to pick up!

      Just simulate the process and use ordered ser from gnu pbds

        How do you simulate the process using ordered_set for n=10^9?

          It would be great if you share any of the insights for iterative solution.

              Thank you for sharing, I am aware of this blog and solution it contains is recursive. I am looking out for iterative intuition.

                copy paste the code given into chatgpt and tell it to do iterative, i think it will work

                  I did that, chatgpt didt went well! GPT is language model, it doesnt understand the logic encoded in some kinda variables!

Recently, I found this solution online, anyone can decode it?

    I see some kind of pattern author is trying to code, is it?

      I also followed the solution suggested by drugkeeper . It's neat and clear. I can try explain it to you . Why are you bothered to find iterative one?
