Hello, people.
Does anybody, who solved 1025 problem, know why wrong answer on test1?!!!!
I'm sure that my solution is right, but may be i don't know some exceptions ??  For example how to write the right answer in file...
I'm a novice in this site, and on my PC the solution solves the problem correctly!!!
Please, help if you can!!!!!!!!!!

Check your input and output. If I remember, test1 is sample input from problem text.
