Re: Problem 258

Hi,

Can someone please write lfousse's code (2nd post in the solution forum) in mathematical notation? I've left a query at the end of my post (currently the last post) in the solution forum outlining my current understanding.

Thanks,

Re: Missing Wedding Ring Finger

Maybe this works: The man who gets of the train with the woman is her husband, but he has multiple personality disorder. He has two personalities, one a normal caring husband, the other a viscious violent mysogynist. His mysoginistic personality has flared up in the past (hence the missing ring fing...

Problem Release

So when are new problems released? There's no countdown for 439 yet. What's the interval between the release of two consecutive problems?

Re: Throw in the towel option?

I definitely do not think that there should be a 'Give Up' or 'Hint' button. It would lessen the challenge and discourage perseverance. In my experience, I have encountered problems that initially I had no idea how to do and probably would have gladly clicked a hint or give up button, but after some...

Problem 253

Could someone verify these numbers:

For n=30, M=2, the number of possibilities are 7968620985557942272

for n=50, M=2, the number of possibilities are 252563827221661992872589320519680

Re: why don't solver annotate their solutions?

Lol, because we're lazy! Who can be bothered to annotate their code? Often, if you understand the solution, you'll be able to understand the code, at least that's what I've experienced, unless of course they use some weird programming technique, though it'll often be mentioned in the forum and you c...

Re: What is the best language for Project Euler?

I've used python to solve all problems I've solved so far. And they pretty much all are under a minute. @PurpleBlu3s : I see your point but I'm not sure I agree. In fact *every* language is suitable for PE especially at the begining but from my own experience I solve around 120 (more or less) proble...

Re: Graph of the Statistics

The graph looks great! If there's one thing I might suggest, it's that maybe a line on the 0-100% graph could be also plotted at 2%, to give a better sense of scale of the second graph.

Wow, I find that ironic that the private area is more 'active' than the public. Although it just goes to show how much you guys work on this Project :D. It's not your bad at all. Thanks :). I just didn't want to seem unappreciative of your effort, and in hindsight the suggestion was rather silly, as...

Re: Functional requests

There's one caveat. Obviously one can only estimate a problem's difficulty correctly after having solved it. That would mean that the population that voted for a problem's difficulty isn't representative for 'the average Project Euler user'. Hmm, I hadn't thought of that! Oh, well... I wish there w...

Re: Functional requests

Any difficulty rating system would be entirely meaningless, even if problems were ranked by those who solved it. Some people even have difficulty with Problem #1. How would they rank it??? Alternatively, some people have solved over 300 problems within a few weeks. How would they rank them all??? A...

Re: Functional requests

I have two suggestions: My first suggestion is whether we can implement a difficulty rating system for problems. Users who solve a problem can then rank the difficulty of the problem, easy medium hard or out of 5 stars etc. and on the problem page it would display the average rating, thus providing ...
