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.
