483 PE
i deleted all white spaces.
what i should do more to get AC.

[emotional blind]

you cant delete all white space,
when some white spaces are needed for the output to get accepted
you should remove unnecessary white spaces and
unnecessery blank lines.. ok?

The last output don't should be:

I submit this code and i get WA, WHY??? It's a problem so easy!!!!!!

Code: Select all

#include <stdio.h>

//483

int main()
{
        char c, s[100]; int cant = 0;
        while ((c = getchar()) != EOF)
        {
                if (c != '\n')
                {
                        if (c != ' ')
                        {
                                s[cant++] = c;
                        } else
                        {
                                for (int i = cant - 1; i > -1; i--)
                                        printf("%c", s[i]);
                                cant = 0;
                                printf(" ");
                        }
                }
                else
                {
                        for (int i = cant - 1; i > -1; i--)
                                printf("%c", s[i]);
                        printf("\n");
                        cant = 0;
                }
        }
        return 0;

Have you tested it with different inputs and outputs before submitting.

Try putting the sample input in a file in the same directory as the executable. Then run

'YOUR PROGRAM NAME' < 'INPUT FILE' > 'OUTPUT FILE'

and see if you get the same as the sample output.

[neno_uci]

Try to increase your array size, I used 10000000 chars but I guess 1000000 will do..., good luck,

Yandry.

[BenderBendingRodriguez]

I have two questions to this problem:

1.) What if there is one or more blank lines in the input?

Code: Select all

bla blob blub


123... 0.98

2.) what if there are more than one white space characters between words in a line?

Code: Select all

bla                                   blob                                  blub

why wa ?? i can't find bug. thanks.

[Darko]

When they say "whitespace" instead of "space" that means that they will use any whitespace (I check for '\t' and '\b' on top of those that you check).

[alfreadx]

thank you.
i got AC bot PE.
that's ok.

[mosaick2]

I have tested all sample that I could find below articles.
And I have passed the testcases.
BUT, online-judge give me W.A(Wrong Answer)
Frankly, I believe online-judge. So I think I have a fault in my program.
Who can give advice me aboue this?
Thankx, your help. : )
