Problem Statement

You are given a non-negative integer N. Print all non-negative integers x that satisfy the following condition in ascending order.

• The set of the digit positions containing 1 in the binary representation of x is a subset of the set of the digit positions containing 1 in the binary representation of N.
• That is, the following holds for every non-negative integer k: if the digit in the "2^ks" place of x is 1, the digit in the 2^ks place of N is 1.

Input

The input is given from Standard Input in the following format:
N

Output

Print the answer as decimal integers in ascending order, each in its own line.

Constraints

• N is an integer.
• $0 \le N < 2^{60}$
• In the binary representation of N, at most 15 digit positions contain 1.

The binary representation of N = 11_{(10)} is 1011_{(2)}.
The non-negative integers x that satisfy the condition are:

• 0000_{(2)}=0_{(10)}
• 0001_{(2)}=1_{(10)}
• 0010_{(2)}=2_{(10)}
• 0011_{(2)}=3_{(10)}
• 1000_{(2)}=8_{(10)}
• 1001_{(2)}=9_{(10)}
• 1010_{(2)}=10_{(10)}
• 1011_{(2)}=11_{(10)}
