But I keep on getting PEs???

I'm not sure, that one seems to be OK - do you print "ERROR" or " ERROR"?

[daveon]

Well, I used

Code: Select all

cout << "  ERROR" << endl;

[daveon]

Nevermind, I recoded it in C and got ACC.

Not nevermind!! Please, tell me the number of submission so that I can check it. Or send me the program.

Going through my PE programs and I have PE for this problem as well.
Using C++/STL, I thought that maybe setw in combination with string could be a problem but the following gives PE too:

Code: Select all

struct Solution {
	string number;

	friend ostream& operator<<(ostream& strm, const Solution& solution) {
		if ( solution.number.length() > DIGITS )
			strm << "  ERROR";
		else if ( solution.number.length() == DIGITS )
			strm << solution.number;
		else
			strm << setw(DIGITS - solution.number.length()) << ' ' << solution.number;

		return strm;
	}
};

Newline characters are written in main:

Code: Select all

void main(void) {
	transform(istream_iterator<Problem>(cin), istream_iterator<Problem>(), ostream_iterator<Solution>(cout, "\n"), ProblemSolver());
}

The only thing I can think of is empty newlines in the input...

[daveon]

Perhaps I am using incorrect code to output.

The PE code:

Code: Select all

if(error) cout << "  ERROR" << endl;
else      cout << setw(7) << temp << endl;

The AC code:

Code: Select all

if(error) printf("  ERROR\n");
else      printf("%7s\n",temp);

Maybe it's the compilers problem. setw might not be well implemented....that will be solved when upgrading the compiler (new system again).

I've checked judge's output and I couldn't find anything wrong.

We'll leave this for now.
