Lowest Bit
?1000ms??32768K
描述：
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.
输入：
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.
输出：
For each A in the input, output a line containing only its lowest bit.
样例输入：
26
88
0
样例输出：
2
8

最低位
已知一个正整数A(1<=A<=100),输出A的最低位。
例如，整数A=26，我们可以写出A的二进制数11010，所有A的最低位是10，输出应该输出2.
另一个相似的例子是：A=88，我们可以写出A的二进制数1011000，所有A的最低位是1000，所有输出8。
输入：
每行包括一个整数A(1<=A<=100).某行输入为0则代表输入结束，并且0不作为输入数据。
输出：
对于每一个输入A，在一行输出其最低位。
