706 - LCD Display

[regina]

my code may be too long, but still, why 'wrong answer' if it gets the job done?

Ok, I looked at your solution and it's not correct.

1) You don't leave a blank line between numbers.
2) Try the input file with 8 31415 added at the end. Your output should be this (my output):

Code: Select all

      --   --        -- 
   |    |    | |  | |   
   |    |    | |  | |   
      --   --   --   -- 
   | |       |    |    |
   | |       |    |    |
      --   --        --

 ---   ---   ---   ---   --- 
|         | |   | |   | |   |
|         | |   | |   | |   |
|         | |   | |   | |   |
 ---         ---   ---       
|   |     | |   |     | |   |
|   |     | |   |     | |   |
|   |     | |   |     | |   |
 ---         ---   ---   ---

 --------                                    -------- 
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
         |          | |        |          | |         
 --------              --------              -------- 
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
         |          |          |          |          |
 --------                                    --------

Instead, yours outputs this:

Code: Select all

      --  --         -- 
   |    |    | |  | |   
   |    |    | |  | |

See how your 3 is smooshed up against the left edge? That's part of the problem. I'm not sure where in your code is causing that, as I admit I don't understand your code, but now that you at least know where you're going wrong you should have a better chance of fixing it.

(Also if you're posting code, remember to click Disable Smilies. Makes it easier for someone trying to help you to get your code )

[regina]

Hi - thank you so much! My program just got accepted (with a P.E., but I really don't care about that so much) . The picture in the problem description threw me off -- it would've been better if the spaces were substituted with * or something... If it wasn't for your help, I would've probably never even seen it!

BTW -- my code is pretty easy - instead of focusing on full numbers, I reduced them to dashes and vertical lines, so every time a number came through, I just threw out a bunch of dashes and lines that corresponded to that number. It was pretty easy to write that way.

[cometx]

The only thing in my code I suspect is how I open the input file, I use ifstream instead of stdin. How do you open the input file the way they want, please advise.

[GreenPenInc]

You have to use standard input for input and output to standard output. If you are using unix or linux, do:

Code: Select all

prompt$ ./a.out < input

Where a.out is the name of your compiled binary and input is a file containing the test input.

[GreenPenInc]

Glad I could help.

btw, check out a program called figlet. If you use Linux it's probably already installed. It's a fun little thing to play around with, and is similar to this problem.

[Eduard]

Hi.
To Pasq.
On your program Jakie can have some ' ' .
Thats way you need this.
And yuo will get AC(P.E.).
[pascal]while wie>0 do
begin
1:
for i:=1 to length(jakie) do
if jakie=' ' then begin delete(jakie,i,1);goto 1;end;
jakie:=' '+jakie;

[/pascal]

The whole code will be.
[pascal]
program dupa;
label 1;
var
wie :longint;
jakie :string;
i,j :longint;

jakie:=' '+jakie;
pelne:='';
puste:='';
n:=length(jakie);
for i:=1 to wie do
begin
puste:=puste+' ';
pelne:=pelne+'-';
end;
for i:=2 to n do
begin
write(' ');
case jakie of

[jagadish]

i dont understand pascal but i complied your program and found that its
far from being correct ..make sure that you atleast check your code with
sample inputs before making a post

[tan_Yui]

I executed your code, and got wrong output.
Check your code again.
If you can't find wrong point of your output, check with other compiler or text-editor will lead you better.

I got AC(P.E) in this problem.
I only change【printf】for【putchar】in C.
You can try it......

[gmenhorn]

Can someone please help me figure out what is going on with this problem. Do we have to handle wrap for numbers that won't fit in 80 columns? (I've tried it with and without wrap to no avail). Every test case that I can think up works fine. Is the problem statement really that clear that I'm missing something so obvious? Thanks a million for your help!

Here is my input file:

Code: Select all

2 12345
3 67890
10 99999999
10 0
5 1094
4 11111
3 18818818
1 0
2 0
3 0
8 31415
0 0

Here is my output file (assuming wrap at 80 chars):

Code: Select all

      --   --        -- 
   |    |    | |  | |   
   |    |    | |  | |
