you should consider leading zeros.
I mean when input is 007 output shouldn't be as same as when input is 7.
you could get the No in string and for checking end of inputs it is enough just to check s.
I hope it could help.

Not true, this is what my accepted program does. Both these cases should print out a 7.

I don't understand what you mean here. "0 3" as input should not end the program.

Note: this only applies to the http://www.programming-challenges.com site:

If you take a look at the statistics for this problem on the programming challenges, you'll notice this:

Best time never solved

Probably there is something wrong with the judge script on the site.

Its been awhile, but I will comment.

The max digit per the specification is only 8 decimal places. Your code prints more than that.

There may be other issues, such as trailing spaces or error condition handling (though the spec does not mention anything about such issues).

ok, good luck if you have not already solved this one.

try to print your output in a file.

when i tried to print output for your program in a file it prints nothing. (I use Visual c++ compiler).

Posted: **Sun Dec 03, 2006 7:49 pm**

try this input

1 0123456789

your code prints only

Posted: **Sun Dec 03, 2006 8:02 pm**

opps i forgot to write output of your code for my input

it prints only only 9

Posted: **Thu Dec 21, 2006 3:09 am**

winkle, the mistake is that you forgot to do (length = len) when (n == 0).
Then, you may pass the wrong value of length to draw_digits.

I am getting Presentation Error in LC Display ( 706). I think I handled all types of mistake which can be the cause of P.E.
But I am getting it for everytime.

Can anybody help me?

Here's my code.
