some critical i/o can also help?i have tried with all sample i/o s given here.

Anika, at first search the board for existing topics before creating a new thread.
And before pasting your code, click on the "code" button above, or else your code will loose clarity due to omission of the whitespace and tab characters.
i found no other thread for this problem 10113 except this ...
