I've been cranking down hard on some of the easier problems (I'm still stuck on a few of the 300's that I find interesting) -- just did 216 myself and pretty much bruteforced it (lame).

I did the same thing. Felt lame as well but hey, at least we got the answer haha.

EDIT: Got #179 just now.

Pumped out a few more today... 137 was a bit of a challenge, but the solution is an interesting one. I'm only on page 4/8 of total problems (when arranging them by # solved) and the questions are definitely getting tougher. Problems 338's been out since May 2011 and it still hasn't reached 100 solvers yet. 344 looks beastly, too.

Hit level 7, going to bed.

I tried, but because I can't do math for the life of me, I ragequit.

Just solved p357. Could've solved it faster but I was being dumb... oh well.

Re: THE project euler thread
 
Got 357 as well. I should try thinking of more efficient ways of solving it.

This looks cool, I might start working on these when I have time.

is the answer less than 1 million

Nope.

Hint below for generalized elaboration, however:

I remember this problem, though -- IMO it's a poorly-designed one. You can make a really stupid assumption about the answer and it'll turn out to be correct and save you a hell of a lot of runtime. Similarly, the problem is more programmatical than mathematical. You can brute force it (using a non-naive approach) in just a couple seconds (given the stupid assumption).



Stuck on 152, which is silly because it should be easy

Just did number 15. I thought it was a little too easy; there wasn't even any programming needed to do this problem.


Starting in the top left corner of a 2x2 grid, there are 6 routes (without backtracking) to the bottom right corner. How many routes are there through a 20x20 grid?

Solved 349 -- posted my solution in the thread (check if out if you get the chance -- it has a nice pretty text output, haha)

Yeah the earlier problems are kinda stupid simple sometimes, but only because they're the early problems.

level 7 !! \o/

Re: THE project euler thread
 
I still don't have 356 or 152 :<

leonid 11-12-2011 08:45 PM

Re: THE project euler thread
 
Got 358 \o/
