Thanks, I already thought of this one, and expected everyone would do With a double for-loop.. Anyway, we'll see who can do it in 1 for-loop  |

You've a long way to go yet! (53 bytes) Nothing like throwing weighted dice to make sure you win  (no peeking @ the solution Riven  ) |

How many bytes?  (Should I be worrying about a StackOverflowException  ) |

How many bytes? (Should I be worrying about a StackOverflowException ) Sounds like you are on the right track I think it's a more scalable solution than one using a stack of byte[99] |

got 54 in reverse with a correct comparison c>-1 and 53 with the slightly incorrect one c>0 Was pretty easy to get there. |

And here was my initial attempt: 1
2
3
4
| int[] a = new int[99];
for(int o=1;o>0;)
if((a[o++]=in.read())<0&&(o-=2)>0)
out.write(a[o]); |

I was working on this 63 byte solution: 1
2
| byte[] b = new byte[99];
for (int s = in.read(b); s-- > 0; out.write(b[s])); |
but got 53 as soon as you mentioned StackOverflowException |

At the moment, you can create an account and submissions will be logged to determine how many people did better than you (if any). If you're not logged in, all your submissions will be assigned to the default anonymous user. http://213.247.55.3:8484/compileandrun/I made the statistics abolutely anonymous, so you only see how many people had their *best* solution better/equal/worse than you. No need to post your code again, to prove that you really got it down to so little bytes. All I can say is, that it is a royal PITA to program a dynamic webpage in Java (without a framework).
Java is simply not suited to handle much text in your sourcecode.
I'm so fed up with Java in this project, that I'm going to convert it to PHP with a Java part that handles the compile&run part.  |

It's great that you've added accounts now. Super work. IMHO, it would be even better if you showed the best/equal/worse statistics next to the names of the challenges in the main /compileandrun/?account page. Then you'd know instantly which ones you needed to work on to try to beat the best score. Cheers, Tim. |

Good idea, I'll do this tonight, before the major overhaul of the site.
I just had my exams, but this week I'm dedicated to a project at school, so again... there is limited time to get things done.

this is pretty cool, but i am no good at optimizing. my attempt at the capitalizer was 113 bytes.

Hm... I wonder when I'll have time to finish this one. Having two jobs and a full-time study pretty much consumes all my time  Oh... ehm... I just noticed the SQL connection got a broken pipe after 1 day Gotta make it reconnect eh? Update: It reconnects now... I already wondered why nobody was registering accounts... I thought it was pretty much dead. |

Yeah... debugging something that happens hours later, aint much fun.
When I have time, I'll convert it all to PHP with a Java backend - as I said earlier.
It should be pretty darn easy and quick to do... but don't hold your breath.

I know I'm late, but I just stumbled on this thread and found it very interesting. I'm not very good at it, but I got most challenges down to a decent size.. I had a VERY hard time with the hex one.. I dont know bitwise operators very well, so if some of you could please explain your logic with the hex challenge, I would be grateful for the lesson! here's my solutions: 1. Capitalizer (71 bytes) 1
2
3
4
5
| int a=0,b=0;
while ((b=in.read())>=0) {
out.write((a<33&&b>96)?b-32:b);
a=b;
} |
2. Reverse (93 bytes) 1
2
3
| int b[]=new int[4<<6],l=0,x;
while ((x=in.read())>=0)b[l++]=x;
for (x=l-1;x>=0;x--)out.write(b[x]); |
3. Hex (231 bytes) ( note: for those who are curious about the 4<<6, that's just a cheap way to get a 4-digit-sized buffer (at the time I didn't know the scenarios were not dynamic..) 1

| int b[] = new int[4<<6];
int x,l = 0,y = 0;
while ((x = in.read()) >= 0) b[l++] = x;
for (x = 0;x < l;x++) {
if (b[x] >= 48 && b[x] <= 57) {
if ((x+1)%2 == 0) y+=b[x]-48;
else y = b[x]-48<<4;
}
else {
if ((x+1)%2 == 0) y+=b[x]-87;
else y+=b[x]-87<<4;
}
if ((x+1)%2 == 0) {
out.write(y);
y = 0;
}
} |
4. ByteSwap (63 bytes) 1

ok, I managed to get my hex solution down to 133 bytes, but I'm still baffled as to how the rest of you did it: 1
2
3
4
5
6
7
8
9
| int x,y,z = 1;
while (z > 0) {
y = 0;
for (x = 0;x < 2;x++) {
if ((z = in.read()) < 58) y+=(x>0?z-48:z-48<<4);
else y+=(x>0?z-87:z-87<<4);
}
if (y > 0) out.write(y);

Nice tries! A bit large answers, but at least your code is butt-ugly, which is what this contest is all about If only I had some free time to build this into a proper 'service'...  |

So the server went offline for good or is the project alive somewhere else?  Also, was the server even been hacked or did your code successfully prevent that? |

Believe it or not, it never left my mind! I've been trying to find the time to make a proper implementation. It's way too much fun! It's not too hard to code it, but coding the whole user-interface and what-not is boring and timeconsuming. Give me a few more weeks |
