OJ Board

ACMIO is not a standard java class. In fact, I'd never heard of it until I looked it up on google. UVA is very picky about the classes that they support, and very behind the times. I've written some methods that do similar things to ACMIO ( check this board under "[JAVA] Useful methods to save ...

Think of it as like printing on a typewriter, there are two different things that you have to do for a line to be printed. You hit enter and it takes you down to the next line. Then you push the roll back over to the other side. These commands are called line feed and carriadge return. you're escapi...

I've had similar errors like this using UVA's java compiler. Sometimes a program will crash or perform differently when running a command on one line instead of breaking it into seperate lines. Logically your code should be, and (using a good compiler) is the same, but their compiler must mix up cod...

Yeah, well I got screwed by the actual ACM regional competition judge. I submitted a problem in java and I kept getting "Incomplete Output." Turns out my problem was crashing out early because I didn't make my array large enough. So we coded it out in C++ and quickly found the error. So ye...

I wrapped your code in a try/catch block and had the catch do a while( true ); The purpose, well, if you're currently getting WA, then if an exception is thrown, you'll get TLE instead. But on your program, no dice. It still exits after like 1.3 seconds with WA. Looking through your code, I don't se...

I feel like a broken record. Most of the java.util functions don't work with UVA's java compiler. In addition, they are running a gcj compiler that supports some java 1.2 functions, so if it was added in 1.3 or 1.4, tough luck. It's also a pain in the butt trying to use one of the few things that th...

This is due to poor java support of the UVA judge. java.util.Arrays and java.util.Comparator are not supported by the judge. Pretty much anything not available in Java 1.2 isn't supported, and a good portion of 1.2 isn't supported as well.

This compile error is given by the judge when you try using a function that isn't recognized by their compiler. Sure enough, your code compiles fine using the standard java compiler, but the judge's Java support sucks. Note to judge: Quit upgrading your Pascal compiler and support some real java alr...

The problem lies with how they run the code. You're getting a wrong answer because it's printing out the error message. It doesn't throw errors back to the operating system like C or C++ code. It just keeps it in the Java environment. So basically, the only thing that the operating system sees when ...

To the best of my knowledge, all UVA problems are reading from standard in. This problem was probably taken from an actual ACM competition, which, at least around here, read from a file. ( generally 'a.in' and so fourth ) Try solving the problem reading from standard in. Post again if you're having ...

Thanks, worked.

Yeah, 1:40 AM here, so what's going on?

Grr... no clarifications either...

I can't view problemset. It says 404 Not Found. Anyone else have this problem?

Yeah, problem seems pretty straight forward, but I keep getting WA... [java] class Main{ public static void main( String[] args ){ //0123456789012345678901234567890123456789012345678901234567890123456789012345678901 String idx = "ABCDLMR***EPST*N****IFK*******OVG*******UJ********YQ********WX***...
