A positive integer N is said to be a "round number" if the binary representation of N has as many or more zeroes than ones. For example, the integer 9, when written in binary is form, is 1001. 1001 has two zeroes and two ones: thus 9 is a round number. The integer 26 is 11010 in binary; since it has two zeroes and three ones, it is not a round number.
INPUT
