Problem description 
Given an positive integer A (1 <= A <= 10^9), output the lowest bit of A.
For example, given A = 26, we can write A in binary form as 11010, so the lowest bit of A is 10, so the output should be 2.
Another example goes like this: given A = 88, we can write A in binary form as 1011000, so the lowest bit of A is 1000, so the output should be 8.

Input 
Each line of input contains only an integer A (1 <= A <= 10^{9}). A line containing "0" indicates the end of input, and this line is not a part of the input data.

Output 
For each A in the input, output a line containing only its lowest bit.
