### Re: Error in solution to problem 8

Hi hbhatia, Welcome to Project Euler! I have verified that the answer on the site for 8 is indeed correct. Note also that it has been solved by 351674 people already. If you'd like to send me a private message with which 13 adjacent digits of the 1000-digit number give rise to your answer, I'll take...

No worries! It's applied retroactively, so you are now appearing in the list for 726 at 52nd.NaoisTheGuardian wrote: ↑Sun Sep 20, 2020 12:35 pm Ah, thank you! I'll just have to try and get on the next problem's list haha

### Re: Not appearing on the fastest solver's list

Hi. I recently completed problem 726. I was 51st or 52nd to solve it, but my username hasn't appeared on the list. I can't think of any reason this might have happened other than that I am currently not yet level 1? Anyway, thanks in advance. Welcome to Project Euler! In order to appear in the "fas...

Maths formulas were not rendered and code sections would not open. Thank you for reporting this. I cannot load the thread either: the Chrome tab...

### Re: Problem 610

The question states The rules do not place any restriction on the number of occurrences of M, so all integers have a valid representation. but doesn't explain how to get negative integers, and I got the tick with an answer which assumes that negative integers don't have a valid representation. I th...

### Re: Problem 684

Do you have to find the smallest digit sum for each term of the fibonacci sequence from the 2nd to the 90th? No, that is not correct. $S(n)$ is not digitsum. Instead, $s(n)$ is the inverse digit sum, so $\mathrm{digitsum}(s(n)) = n$. Note also that $S$ is the sum of $s$. So, (given a Fibonacci numb...

### Re: Problem 689

Your values of $f$ are correct (albeit with the interpretation of the $\pi^2/6$ value as a limiting case, because $f(x)$ is only defined if $x$ is strictly less than 1).

For answer format, the leading zero is required, as in 0.abcdefgh

At this point, I'm about 1 step away from challenging the answer to this problem. I know a fair number of people have already solved this problem. I know I have everything in correctly, the program appears to operate just fine. I've done just about everything I can. Next step is to verify each step...

### Re: Bookmark / Pinning a problem?

To answer your original question, the Project Euler site does not currently have any specific functionality for bookmarking problems (except for "filter by solved/unsolved"). The work-around I suggested earlier of using browser bookmarks may still be viable for the cross-device use case that you des...
