Project Euler Forum

>>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'

You're being asked to decrypt the given message. As answer you must give the sum of the ascii values of the decrypted text.
Easier we can't state it.

The order of the last sentence of Problem 81 (View Problem), Problem 82 (View Problem) and Problem 83 (View Problem) has been changed in order to address the possible confusion rows vs columns in #082.

Why are you assuming that English isn't my first language?

Is it then?

A few things must be made clear: The projecteuler.chat forum (that's the forum you are reading now) is an out of the box forum. It uses phpBB. We can't change that forum to accomodate for requests. The main site projecteuler.net is written by Colin Hughes himself. Reasonable request can be catered f...

Perhaps it's good to add that "integral" can also be a noun.
E.g the concept of an integral in Calculus (an antiderivative used to calculate an area and other uses) .
However, in the wording of problem 94 'integral' is an adjective.

Hello, I have two issues/bugs: 1. I have solved 100 problems already, but if I check my position in statistics/locations it says I only solved 99 problems, is it a sync issue? Yes, I think so. Should be OK now. 2. I got the "On The Ball" badge even though I didn't deserve it, can you remo...

They should have stored that somewhere in a safe place.
This is the one and only way to recover the account avic.

The problem isn't about adjacent numbers but about adjacent digits.
