I've changed my code. But wa. Maybe some problems with reading strings. Who can give some input tests?

Code: Select all

removed, after acc...

In one day third time i make same full mistake, not removing comments and read/write from files.

// #ifndef ONLINE_JUDGE
freopen("input.txt", "rt", stdin);
freopen("output.txt", "wt", stdout);
// #endif

No The above code is still getting PE .. Can you tell wts wrong in that code.
Please ..
Thanks

I saw on uhunt that you already got AC on this problem.

Try changing your input parsing. I got AC reading the input as strings, not line by line.

Posted: **Fri Dec 12, 2014 10:02 am**

Code: Select all

Accepted !

Posted: **Fri Dec 12, 2014 10:55 pm**

Input:

Code: Select all

a b c d e
#
b c d e a
#
a b a a
#
a a
#

AC output:

Code: Select all

b c d e
a a
