Problem 208 (View Problem) too (although I needed a little help from excel )
Fun problem! The paper/pencil solution posted on the solution thread is brilliant. I did however find the group presentation

Interesting that I just recently revisited this problem to remove my use of BigInteger; it didn't occur to me.

Even though my response is a year late, I hope it helps.

To mods, is my solution good enough for an overview? I know you only publish overviews when someone volunteers

Problem 188 (View Problem). Nice to stumble on one after a year-long hiatus.

And Arancaytar mentioned solving Problem 282 (View Problem) on paper.

### Re: Problem 185

I just solved it but continued to play around with it to see if I could reduce the runtime. Against my own intuition (or logic? because it must have been intuition that made me try), I arranged the attempts in descending order of correct digits. This reduced the runtime by a factor of (almost) 10! F...

So I've read that there's nothing that rules out time travelling, but there's something I've never seen discussed: mass-energy conservation. Let's say in the year 2020, a time machine/portal is created and Sam moves back to 2010. He then lives the next 10 years doing doing whatever he likes. By the ...

### Re: Paper/Pencil Problems

That's how I solved the problem too. But to find "it", I had to use bruteforce like most did on the forum. Can you do find it with just paper/pencil?

### Re: Paper/Pencil Problems

Added. Sadly, I didn't get to read your suggestion. Would it be ok if you posted it on the Problem 321 (View Problem)? It's the only unarchived thread for those three.

Thanks.

138 & 139 simplify to pell's equation which can be solved on paper. Your examples give pell-like equations but not doable without a computer as far as I can tell.

Those forums seem to be active only when the problem is released. I was hoping someone who understands it would send me a PM, not discuss it here.

But now, i'm more or less amazed that something close to 5,000 people have written solvers... Don't be. I solved this with brute-force which didn't require much thought, and my guess is that's the route most of the 5000 took. It's not solving the same way, people do. Now that you mention it, I migh...

### Re: Problem 181

Can anyone explain to me the C code Robert_Gerbicz "translated" from posted PARI solution? I don't mean explaining what the code is doing (C is very similar to Java so I was able to implement it) but explaining its relation to the problem.

Thanks.

Please move your solutions' source code to a private repository. That's how I save mine; now anyone can find your solutions even on Google.

### Re: how fast did you reach level 1?

I remember reading that too. It was in the solution forums. Totally amazing. The difficulty aside, my motivation is also slowly draining. I'm afraid I've done too much computational/analytic programming, but have not created actual software. I'll try and persist till 200, then take a break. Oh, anot...
