Re: Problem 728

You're right.
However, after the correct answer was on the site the number of correct answers grew rather fast.
The difficulty is measured as the speed of solutions not the number of them.

Re: Problem 728

10 weeks after publication a problem is moved from recent problems to the archives.
At that moment a difficulty assessment is automatically calculated.
If there are less than 100 solvers the assessment is temporary.

Re: Solving with pencil and paper

The programming language that is shown is the 'preferred programming language' not the actual language used.

Re: Unit cube roots in number theory

if $p\mod 3=1$ there are three solutions, if $p\mod3 =2$ there is one solution to the equation $a^3=1 \mod p$

If you select 'Active members only' (on the statistics start page) active Python members can be displayed.

Re: Problem 034

Please don't start a new topic for a problem if there exists one already.

Personally I think the choice mathematicians made is not arbitrary, on the contrary.

Re: Errors/Warnings/Bugs

Same problem here. (both on Chrome and Edge)
Other pages using Mathjax load perfectly. Even the second page of the forum for Problem 497 (View Problem) loads without delay.
The page hangs in the middle of the post by nhmllr.

Re: What is the best programming language ?

In Vietnamese I guess.
Perhaps you should go elsewhere with your question.

I don't think it is a good idea to spread the discussion over several threads.

Re: problem 452

You can find out by trying both options for F(10,10).
Somewhat higher in this thread you can even find smaller cases to verify which of the two options holds.

Re: info about previous version of projecteuler site

As far as I know there hasn't been changed anything to the pdf's.
And I would certainly not call them horrible, unformatted and what you were calling them further.
Are you sure you are referring to the same documents?

Re: Problem 059

Many languages have an operator that takes two integers and calculates the bitwise xor of those two integers.
That saves the tedious converting to binary and back.
In many languages that operator is ^. (C and derivatives, Java , Python)
In your case that would be: 72^97 which gives 41.

Re: Problem 054

There's actually no need to have looked up the answer somewhere.
Some people simply try some answers around the value their program gives. Just to rule out off by one answers.
