Re: Problems with [code] statement

I think the closing tag needs to contain '/code' rather than '\code'. In the thread for problem 633 in the forum, I posted my solution: https://projecteuler.net/thread=633;page=2#316037 The problem is that the "code" token or "code=Matlab" doesn't work: the token is printed out, and the code followi...

Re: Problem 353

Are we supposed to calculate every single integer set of coordinates or are the only coordinates going to be (0,r,r) and stuff like that The admissible paths (from which you are asked to find the one with the lowest risk) are permitted to use any of the integer-coordinate points on the surface of $...

I'm getting an answer, but it's not correct. However I'm able to produce the correct number when p < 10^2. Can someone confirm if the next few powers of 10 are correct?
I've removed your values from public view, but I can confirm that they were all correct.

Re: Problem 301

Ah, I see. Nevertheless, the question is correct as stated.
{0, 0, 0} is a losing triple, but it does not count towards the answer.
If people need to count it to get the correct answer, it is likely they have an off-by-one error elsewhere.

Re: Problem 301

I'm happy to clarify that {0,0,0} is indeed a losing triplet. The player is "unable to move (because no stones remain)".

I expect your calculator is rounding to ten significant digits, so the fractional part has been truncated.

Dear Liad777, I have moved your post to the existing thread for this problem.

Re: why are hints for solutions not allowed?

Project Euler's approach has always been "If you can't solve it, you can't solve it", which is why PE does not provide an open forum for discussing solution methods.

You may be interested in this thread, in which a tangentially related point was discussed.

Re: Problem 493

This is indeed the correct forum for discussing issues with understanding the wording of a problem. The problem only talks about the number of distinct colours in the draw. So, whether the balls have any other distinguishing marks (aside from their colour) is irrelevant. The order of the draw (and w...

Dear Omri_Shavit,
I moved your post to the existing clarification thread for this problem.
Based on your workings for the first 13 cases, you understand the problem statement correctly.
Moreover, the continued fraction you provided for 9999 was correct - but your overall answer was much too low.

My thoughts concerning the sample numbers from the description: 9 is in the list because with d=2 we get q=4, r=1. For this [1,2,4] there's the factor 2 forming this geometric sequence.

Am I right with this? Or am I completely going wrong?
Yes, you are correct.

With regard to the earlier comments in this thread about characters versus symbols for variable names, the problem description has now been amended to specify that a variable is a single letter (drawn from an infinite alphabet).

Also, $\Lambda(n)$ is described as the number of distinct $\alpha$-equivalent lambda-terms that can be written using at most $n$ symbols, but it's actually the number of such symbols which are closed .
