Is there a way to subimit a code in Python? And if not, is there any site like UVA that accepts python codes?

Yeah, that's exaclty the case. I tested with the values on "Algorithmist" wiki and using 'double' as variable type it will not be precisely enough.

Does it work if I use "double" as variable types? I don't know how to use this BigNum thing yet, I'm still learning C and I just want to practice.

UVA's g++ and gcc have int=32 bits, long=64 bits, long long=64 bits. The reason int doesn't work for this problem is if you try and add or subtract 32-bit signed int's you may get overflow.

You are right. I compiled a simple program to test C data type under Linux, with GCC 4.4.5-8, and here is ...

To check if the sides form a triangle, you should performe 2 tests:

1. See if every input is greater than zero
2. | b - c | < a < b + c

I compiled it under Debian Linux and it worked just fine, thanks. But when I'm in Windows, I might use Mingw. If I need lcrypt in the future, I'll try to install it.

I think in Windows the specifier for long long int is %I64d and for unsigned long long int is %I64u . This is the code and its output in Windows:



#include <stdio.h>
#include <limits.h>

int main()
{

/* header */
fprintf(stdout, "%22s | %8s | %7s | %4s | %19s | %20s\n", "DATA TYPE", "printf ...

Use long long instead of int.

You are right, I've just got an "Accepted" when I changed int to long long . I tested if I could have declared just as long , and I got accepted too. So, it doesn't have to be long long , it can be just long . It seems that UVA's gcc specifies 16 bits for int ...

Thanks, but Cygwin has the same error about lcrypt.

Question: how to input/output " long long int " and " unsigned long long int " data in a portable way using C language?


I'm currently compiling in Windows XP with Mingw and I'm trying to use %lld and %llu . Here are the code and its output:

#include <stdio.h>
#include <limits.h>

int main ...

It's working now, thanks!


ps: %lld didn't work on Windows (I had to use %I64d to test), but it worked for UVA's gcc.

I cleared my cookies and now the site is working again, thanks!

I guess I don't need it then, for now. But what if I need this one day? Is there a way to implement it in Mingw?

Whenever I try to access http://uva.onlinejudge.org/index.php I receive this error:

Erro 310 (net::ERR_TOO_MANY_REDIRECTS)

Is the site offline or is it happening only here?

I don't know if I do... what is it for?
