mine too s correct but getting TLE.....

edit: make sure your algo is fast enough
make sure ur I/O is fast enough
in case of C++: use scanf,printf than cin,cout
in case of Java: use BufferedReader than Scanner

I keep trying out my code and I keep getting "runtime error" but when I try to run it locally on my OpenBSD4.8 it works perfectly could we get more accurate sample input like the so could 10000 digits.

YatsukoYin: 2014-05-13 18:20:42

Should we use FFT to solve this problem or something else?
Karatsuba?
