No, you don't wrap long lines; the maximum line length (for an eight digit number) is 8*12+7=103 characters.
Your output looks good, apart from the wrapping.
Are you sure you fill up every line to it's full length, also for 5 and 6 as the last digit?
Are you sure you don't print an extra column of spaces at the end the last digit?
Are you sure you print an empty line (that's without spaces) after each number (including the last)?

That's about everything that can go wrong... your characters look fine.

Thank you very much for your help. I'll try to solve the problem and see what the server says...

Hi joey, thanks for the fast response! To answer your questions:
- took out wrapping
- I'm sure that every line is filled to its full length
- I don't print an extra column of spaces at the end of the last digit
- I print an empty line, without spaces, after each number including the last

I replaced the spaces with period characters to make it clearer how my output looks. The same input from the my previous post was used and wrapping removed. Here are the results. There must be some case that I'm missing but I can't for the life of me figure out what it is. I've read over the description thousands of times trying find what that subtle issue is. Again, thanks for taking a look.

Beats me. Your output looks good.
You can PM me your code, if you like, and I will have a look at it.

How about leading zero?
Your test input doesn't have one input with leading zero.

I am not sure if the input has leading zero, but my code also handled that

My AC program doesn't handle leading zeros (the answer for 007 is the same as for 7, namely one zeven), so I think there are no leading zeros in the input... Good idea, though.

I just rewrote the problem from scratch, submitted, and got an 'Accepted'! The only think that I can think of that is different (don't have access to the old version at the moment) is that I used loops this time rather than use std::string's resize function to create the strings. Maybe, there is some implementation difference in the compiler (I compiled/tested using g++ 3.3.1) or it didn't handle some strange case that I didn't have a test case for. Thanks for your time though.

I got AC now

I've got the same problem as the original poster. The only weird thing I can see in my output is if you try printing a number with 0 size: But then... Will someone that's gotten AC on this problem tell me what kind of output they get for size 0 numbers? Or anyone have any other ideas as to what might be wrong?

Thanks in advance!

EDIT: Here's my code if it provides a clue (with .'s instead of spaces):

this is my code... but it doesnt seem to work keep getting wrong answers

hi randomtaiwanese.

I think you don't need to use such many function, sould use the Display Number template instead.
Try to draw some Display Number by hands.

For example, when the Number is 3 and Size is 1, it is represented by follow.
"." represents a space.
Then you should think the Number 3 in Size=2.
How you draw 3?
Where would be change, and where would be not change?
Think about it, then your souce will get more simple and you will find a bug.

can someone give me some good sample test inputs???

this is my code, and it doesnt work, according to the judge...
