Project Euler Forum

On the Archive page there are up and down arrows above several columns. If you press the up arrow of the 'Solved by' column problems are sorted by the number of solvers in ascending order. If you press the down arrow of the 'Difficulty' column you get the problems sorted by difficulty in descending ...

I don't know if you are aware of the following sites. They might suit your needs better.

S(10)=14 and s(20)=40
below are the values for F:

Vamsi, you aren't doing right to Project Euler. I know quite a few problems on Hackerrank that don't have an editorial (most of the Hackerrank problems based on Project Euler problems don't have one). Moreover I know quite a few online judges that don't have any editorials at all e.g. SPOJ, Kattis, ...

Risking to say something you know already, but did you try to sort the problems on increasing difficulty?
That might reveal some higher numbered problems you could try to solve too.

Because the side of it has length 5.

I don't think so. These problems about continued fractions are meant to invite you to look up the concept.
E.g. from wikipedia. If you do so you will learn the things on the page I gave you fast enough .

Here's some reading stuff:

>>What is the reason that you must share the code on external webpage and then promote it in the solution threads? I have never promoted it. Actually a yes/no game doesn't seem very fruitful to me. @Lilstalker: I've chosen not to go further with this. If Euler (the person responsible for the site's...

No, the given example is correct. The triffle numbers not exceeding 100 are: n sigma sigma(n)/n 3 4 4/3 9 13 13/9 12 28 7/3 27 40 40/27 54 120 20/9 81 121 121/81 84 224 8/3 The answer for 10^6 is also correct. There must be another error in your program. (it is correct that the divisor 10 of 100 sho...

How is a moderator to know if your posted code is only accessible through that link?
Or if that is the case that some other idiot doesn't put this link somewhere else where the whole world can access it?
Come on it was outside PE, wasn't it?

I'll send you a PM.

When we develop problems a tentative difficulty assessment is done (Hard,medium,easy).
When we need a new batch of problems one of the admins makes a proposal from the ready problems according to the HMEMEM sequence, (hard,medium,easy, medium,easy , medium).

Perhaps it is a good idea to share the name of the offending (torrent) extension?

Deleted accounts can be recreated immediately so that doesn't help very much.

The maximum is 63.

The problem says nothing about x. It may have the same digits as 2x,3x,4x,5x and 6x or not. That's absolutely irrelevant.

This means we didn't change anything to your password.
So if you can remember it it should work. Please think hard to remember...

Yes, it concerns all publishing outside Project Euler. If you want to save your solutions you can do so locally on your computer, usb stick or external hard drive. Alternatively you can make your github repo private. Public repos, blogs etc are not allowed. The about page and the message you see whe...

In the big pink box at the top of the page it reads:

'Don't ask for hints how to solve a problem'
