OJ Board

You consider Java an overhead-free language. This is not true. There is runtime data associated with each object. That data is usually needed for garbage collector, reflection, casts, virtual tables etc. This is what you don't see, but what JVM needs when it executes your program. You can ask the ...

Never mind. I found it.

Could you help me with this problem? I receive SIGABRT. Obviously one of the asserts fires. If I remove all asserts I get SIGSEGV which is what I expect. But I can't see how any input can lead to SIGABRT. I tried different input parameters but I couldn't find any that can crash this program.

gcc - you can found which exactly version searching board for "gcc compiler"

very helpful response. you could just write the versoin number instead. the search produces gazilion of results, then you have to read them to fish for the version number. it's time to include this info into faq.

The OJ works on gcc 2.95.

Pardon for my harshness, but gcc 2.95 - it's just a shame! Valladolid is boasting of using the advanced OS and software (http://acm.uva.es/problemset/computer.html), and at the same time - gcc2.95 which is an ancient, ancient compiler. It just sucks, did you know that ...

Well, for the compiler used by the online judge you even don't need to use "using namespace std;".


Because the compiler the online judge uses is not a standard conforming one. And perhaps in replies about compilation errors it shouldn't say that an ANSI C/C++ compiler is used, because it's ...

I doubt it's available.

I think it's better to be portable and use C++ standard only. std::map is not much slower than hash_map after all.

Hi,

The following code which compiles just fine with g++ 3.2 gives me an error from the Valladolid compiler:

01688991_24.c: In function `void print(ostream &, double, int)':
01688991_24.c:21: `::ios_base' undeclared (first use here)
01688991_24.c:21: parse error before `::'

My program works correctly on sample input, but it gets "wrong output" if I submit it. what could be wrong? Are there any special cases not described clearly?
