706 - LCD Display

[A Faltoo Fellow]

Some body plz help me.

I see my propram ok. But the judge is replying as WA .

I think I may have problem in choosing the horizontal & veritcal lines. Some one plz tell me its ASCII code.
( I took them as '-' (minus) and '|' (OR) ).

If I don't have any mistake in symbols. then tell me some critical I/O

[A Faltoo Fellow]

I Have Got it Accepted Now.

[Thozz]

Hi!. I've dealed with ASCII code, blanks, zero size, eight digits numbers... but I always get WA. Does anyone know about the critical input??.

[Jer]

this is my output form :

3 1234567
*******aaa***aaa*********aaa***aaa***aaa
****b*****b*****b*b***b*b*****b*********b
****b*****b*****b*b***b*b*****b*********b
****b*****b*****b*b***b*b*****b*********b
*******aaa***aaa***aaa***aaa***aaa
****b*b*********b*****b*****b*b***b*****b
****b*b*********b*****b*****b*b***b*****b
****b*b*********b*****b*****b*b***b*****b
*******aaa***aaa*********aaa***aaa

I change "-"->"a","|"->"b"," "->"*" (and this's not point)
I want to know the the final " "(space)whether i have to cut it,
and put the text to new line..........

and the 706 prblem is also let me eat "WA" much time.........

[Thozz]

You should complete with blanks your lines till the end. I mean... all the lines must have the same width, and your fifth line:

*******aaa***aaa***aaa***aaa***aaa

is not completed:

*******aaa***aaa***aaa***aaa***aaa******

I still got WA!!!

Er ... :/ maybe you could put some hints for this problem here , for example what to do if the size is 0 , or anything ... thanks in advance

[Thozz]

Hi!. I'm also looking for hints for this problem. I think my program gives a right answer. I've tried with 0 size... but still got WA

Thanks in advance!.

[kiha]

Yupeeeeeeeeee

I got Accepted [P.E.] on this problem. I will try to get AC without P.E. , but I have some hints for you who get WA on this problem :
1) if you write in Pascal [I don't know how is it like in C/C++] and remember the number as a string , be careful if the last character of this string is a white space
2) remember to output one blank line after each test case

I know these are stupid hints already written in the Problem Statement, but in hurry you might have missed them.
If you follow my hints and still get WA, email me [kiha@op.pl] and I can send you my code in Pascal. If so, please create a Subject of the message like 'Problem 706' or anything so that I won't delete your message as a rubbish.

Good luck to you solvers

[Thozz]

Hi!. Thanks a lot for your hints!!. I will try and deal with the problem as soon as posible. Unfortunately, I'm now very busy .

Thanks again!!

[wanderley2k]

I try to submit and only answered is Accepted (P.E). I am test more line in end file and more blank spaces in end line and nothing.

I submit the code in programming-challenges.com and I recived: "Solved"

I don't know what can be?

[soyoja]

Dear, A Faltoo Fellow
Compare with before and after accepted problem, what is your difference points ?
I received all correct answer with my own test data.
But I don't understand why I got WA again and again... T_T
Plz help me.

I actually got mine accepted, first try. It was very gratifying.

That code above is at least twice as long as it needs to be, btw.

Hints? Consider: for a given number (like "12345") you have to print the entire top row before moving on to the top column, then the middle row, then the bottom column and finally the bottom row. Your method will thus need to accept the entire string of the number, in addition to a parameter telling the size (so it knows how much to repeat). Good luck!
