import java.io.*;
/*
Notes:
-Read Long.parseLong(String s,radix) from java API.
-Remeber that int (signed integer)
is in range negative 2^(to the power)31
and positive 2^32.
-Solution of Matthias Neumair is more correct and much
more faster because I used Long.parseLong which will convert
a String of (bits) to long which need alot of calculations
with alot of cpu consuming multiplications, then reconvert
long to BinaryString which also supose to be cpu consuming
-I think you will got C if you write this program as it. so
update it as Matthias Neumair told you.
