Try BufferedReader and StringTokenizer for input parsing. For printing, try the old System.out.print and System.out.println methods.

I had some problems logging into the new judge server. I provided the right username and password but was directed back to the log in page. My account is activated but was locked as I tried many times to get the registration activation e-mail to be sent to the e-mail address I provided. Is it possib...

Hi,

Check this part of your code:

Code: Select all

    char* c = NULL; 
    *c = '\0';

You declared a char pointer c pointing to NULL. Then the next line deferences c (pointing to NULL) and this will give a runtime error.

Hope this helps.

Try the following case:

Input:

Code: Select all

Output:

Code: Select all

Case 1: -1

I believe your code is written for Java JDK 1.5 (Java SDK 5.0)?

The Java compiler in the OJ is gcj, which supports a Java JDK 1.1 and a subset of Java JDK 1.2

For primitive data types the max you can go in Java is 64 bits for a long (which is 32 bits for C/C++).

There are other types such as BigInteger, BigDecimal, to name a few.

I think what you need is something like this:

Code: Select all

int main()
{
    string str;
    while (getline(cin,str))
    {
         if (str.length() > 0)
         {
             // process input
         }
    }
    return 0;
}

This will read until end of file and skips blank lines as well. Hope this helps.

Check this line: level[i-1].member.insert(make_pair(test," ")); It's the only place which has a 2-character string array. You are assigning a " " (taken to be a const string) to a non-const string. Try something like the following: string space(" "); level[i-1].member.insert(make_pair(test,space));

Use operator[]. STL vector's at() is not supported in this OJ

This question has been asked many times before. Search before you post.

One possible reason could be the use of C++ style comments in C code -

Code: Select all

// comment

Usually, this should compile with gcc but the judge's version of gcc won't compile this.

Code: Select all

while (cin >> a >> b)
{
    // process input
}

will work as well.

My AC program has a slightly different output than the one above. My AC program outputs: Jolly Not jolly Not jolly Jolly Jolly Not jolly Jolly Jolly Jolly Not jolly Not jolly Jolly Jolly Not jolly Jolly Not jolly Jolly As for which one is correct, it all comes down to the following input: 1 2 Since ...

Ok, I am certain there are extra blank lines at the end of judge input, but not in the middle, as mogers's sample input suggests. Can anyone verify this? Thanks.

I added in checking for blank lines. And there are blank lines in the judge input. The blank lines occur right at the end of the judge input based on my current AC code which checks for blank lines. I am certain there are no blank lines in the middle of the judge input or my code would have gotten a...

Thanks for the input. My PE code up there crashes for blank lines. But it should have been a WA rather than PE if there had been blank lines in the input?
