<p>So, I found this website yesterday, Project</a> Euler , and am just working through the problems. I figured some of you guys here would have done some of these before. </p>
<p>Anyway, I'm just working through them, with the goal of becoming better at programming. I am going to do CS, and don't have any CS background, so I'm trying to get one. So far I've gotten 16 of them done, but mostly just the easiest ones. </p>
<p>Any of you guys done some of them before?</p>
<p>haha i have done like 10. I started doing them early on in my AP comp sci class, but then I got bored of them. They’re pretty cool, though</p>
<p>I did the first one. Then my inability to program became a problem.</p>
<p>i did them using my head without CS. I got most of them right. Now I’m going to use java. great for computational thinking.</p>
<p>^ Nooo, the point is to have your program do the work. In order to make the program work, you need to know how to solve the problem; if you’re solving the problem in your head, you’re only doing half the work. </p>
<p>I did the first two dozen in java, and another dozen or so in Perl because java sucks. And while we’re on the topic of programming, I also used to be an active member on the DreamInCode forum, in case anyone was looking for a general programming-centered community.</p>
<p>Yeah Java does suck. It’s so limited, I need a better language.</p>
<p>“i did them using my head without CS. I got most of them right. Now I’m going to use java. great for computational thinking.”</p>
<p>How did you do them in your head? Which ones? Personally I’d have some trouble adding up all the primes below 2 million in my head.</p>
<p>Alright, my apologies. Not in my head, that was an exaggeration. I solved the first 3 on paper, while thinking of the process in my head.</p>
<p>???</p>
<p>You actually got answers using pencil and paper, or just figured out what you need to code to solve it?</p>
<p>Both. I found the answer using pencil and paper, but I knew how to code them before I even began to write the problem.</p>
<p>How’d you do the 3rd one? It took me a while, given I’ve now found a much more efficient algorithm for finding primes than I was using for that problem, but still took my computer a number of seconds to do it…</p>
<p>1 Hour of divisibility work.</p>
<p>I just looked and it turns out I did #5, not #1.</p>
