There is nothing else in the file, except maybe for some extra spaces or line breaks.
What das it mean?
Maybe?
#input 1
4
000


000
--------
OR
#input 2
6
000 00
111111

000111

Who solve this problem please tell how read input.
I use
i=scanf("%s",str1);
    if(i==EOF){
        size=1;
        return ;
    }
//while size >1
But always get WA1.
Sorry for my English.

PART of my AC source:
=====================
char *in;

void delete_spaces (void)
{
    int i;
    for (i = 0; isdigit(in[i]); i++);
    in[i] = 0;
}

int main (void)
{
    scanf ("%i", &N);
    in = new char[N + 2];
    gets (in);
    while (gets (in))
    {
        delete_spaces ();
        // decoding... outputting...
    }
    return 0;
}

PART of my AC source:

int main( void )
{
  scanf("%d", &N);
  while (scanf("%s", S) == 1)
  {
    ...
  }
  return 0;
}

PS: I write using C but C++ also compile it.

I am really depressed.
    scanf("%d",&N);
    while (scanf("%s", str) == 1)
    {
        delete_spaces ();
        correct();
        out();
    }
ALWAYS get WA1.
and
      printf("0000\n0110\n1001\n1111\n");
      return 0;
too incorrect
Who has test №1? Please give. lifanov@mail.ru

Maybe first test is not the same as in sample input...
Maybe something wrong with your decoding function?

input string: 001 1 000 111

if you use
scanf("%s",&str);
str="001"

if you use
gets(str);
str="001 1 000 111"

So... ;)

I think this:

...
int n,i,j;
char t[1000],word[1000];
scanf("%i",&n); gets(t);
while (!feof(stdin))
   {gets(t); j=0;
   for (i=0;i<strlen(t);i++)
       if (isdigit(t[i])!=0) {word[j]=t[i]; j++;}
   word[j]='\x0';
   ...
   }
...

would be OK

i'm confusing with your "delete_spaces" function.

void delete_spaces (void)
{
int i;
for (i = 0; isdigit(in[i]); i++);
in[i] = 0;
}

All i got from this source is...
"change the 1st ' ' from the left into '0'."
&
"if ' ' is not found in the line -> add '0' to the right."

So, I don't think "delete_spaces" is a correct function.
