The Project Euler thread

Re: THE project euler thread

Got #205 with pencil and paper. Took forever but at least I didn't have to sleep through my english class hahaha.

EDIT: Just got #53 with pencil and paper :)

Re: THE project euler thread

The problems that I have found to be the most rewarding to solve with pencil/paper rather than coding are: ("*" following the number indicates a high difficulty, "#" following a number represents a fairly tedious problem in terms of manual work)

6, 9, 26*, 28, 29#, 33, 39, 69, 108, 138*#

I have obviously not looked at every problem between 1 and 108, but when I find more problems that can be done with pencil/paper I'll edit this.

Do you know the definition of triangle numbered problem?

Do you know the definition of triangle numbered problem?

Anything of the form k(k+1)/2 for some k in the natural numbers:

1, 3, 6, 10, 15, 21, etc.

Also, got #216 and #218 (o: Thinking about #241 now.

Re: THE project euler thread

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.

Re: THE project euler thread

nvm got it

Re: THE project euler thread

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.

Re: THE project euler thread

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

Re: THE project euler thread

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

[iironiic]

Re: THE project euler thread

Got 357 as well. I should try thinking of more efficient ways of solving it.

Re: THE project euler thread

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