I think your code has problem... I get accepted so everything with CF is ok... But aslo I can't find any mistakes in your code ...

I don't know. But I just submit your code using MS C++ compiler and it gives me verdict Wrong answer. Pretty Strange ..

    When u see print result modulo a nine-digit prime number (1000000007), in case your variables do not overflow, take them long long (maybe it needs BigInteger!).

    I once got idleness limit exceeded verdict due to the problem with array size which i think should be Runtime Error. Here due to the overflow of some variable, if you use that variable for accessing array elements your code may access some negative index. Though i am not sure this may be the reason of getting this verdict. If you learn the true reason behind this verdict please let me know. :)
