Some one please help me to get Acc.
I got wa for this problem.

WA!!!!
I've done all I could. I tested my program with all of test data I could think of and for all of test data here. I read all of posts and couldn't find anything wrong with my solution.
Please take a look at it.

Code: Select all

So many modifications. Removed.

[alirezanoori]

Hello? Anybody there?? If you can't understand my code I'm ready for some explanations!!

[vahid sanei]

Hello? Anybody there?? If you can't understand my code I'm ready for some explanations!!

you should use 2 newline charachters ( cout<<"\n\n";) after each testcase

i get PE(peresentation error)
could you help me ?
and What`s the PE?
here is my code

Code: Select all

Removed After AC

Thanks in advance

Well, I think I output two new lines after each test data. (One blank line after each).
look at the part:

Code: Select all

if(c++ != 0)
         cout << endl << endl;

Do you mean I should use two blank lines after each test data? Does this include the last line?

one of your bugs is " if(c++ !=0)"
"Output a blank line after each number"

Well, I changed the code to something like this, but still WA:

Code: Select all

        printChars(size);
        cout << endl << endl;

[vahid sanei]

Well, I changed the code to something like this, but still WA

you print a space after last digit
you should print space between two digit !!! it was my bug and i think is your bug too,

[Obaida]

removed

[vahid sanei]

your bug is in reading inputs
try these(<space>==' ')

Code: Select all

1<space><space><space>3<space><space>

[Obaida]

Thank you a lot. I got acc.

[alirezanoori]

Well, I fixed all of that. Still WA.
Here's the new code.
One thing I don't know is this:
I should print a new line after each number and print another one between cases? (One blank line between cases and a new line after each test) or I should print just a blank line between each test case.
for example:

Code: Select all

Input:
1 123
1 123
0 0

Code: Select all

Output:
bbbbb-bbb-b
bb|bbb|bbb|
bbbbb-bbb-b
bb|b|bbbbb|
bbbbb-bbb-b

bbbbb-bbb-b
bb|bbb|bbb|
bbbbb-bbb-b
bb|b|bbbbb|
bbbbb-bbb-b
EOF

or

Code: Select all

Output:
bbbbb-bbb-b
bb|bbb|bbb|
bbbbb-bbb-b
bb|b|bbbbb|
bbbbb-bbb-b

bbbbb-bbb-b
bb|bbb|bbb|
bbbbb-bbb-b
bb|b|bbbbb|
bbbbb-bbb-bEOF

Note: replace b with ' ' (space). EOF indicates end of file.
if you use VS you should see "Press any key to continue" instead of EOF.
I tried both but still WA.

Every line in the output, including the last one, should be terminated be a newline character (\n or std::endl) - this is a general convention about text files on Unix.

[alirezanoori]

Well, as I said, I tried both ways and all got WA!
Please tell me what is wrong. I checked all possible ways for input and output. All works.

1) Your programs outputs \0 characters instead of some spaces.
2) Problem statement says "Output a blank line after each number." That means that at the end of the output file there should be exactly two \n characters.
