  Lowest Bit

  Problem 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

  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

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

  Sample Input

  26

  88

  0

  Sample Output

  2

  8
