PROGRAMMING:Lowest Bit

###Task description:
```
Given an positive integer A (1 <= A <= 100), 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 format:
```
Each line of input contains only an integer A (1 <= A <= 100). A line containing "0" indicates the end of input, and this line is not a part of the input data.
```
###Output format:
```
For each A in the input, output a line containing only its lowest bit.
```
###Input sample input:
```in
twenty-six
eighty-eight
0
```
###Sample output
```out
two
eight
```
