Cirno's Perfect Bitmasks Classroom
Description
Cirno's perfect bitmasks classroom has just started!
Cirno gave her students a positive integer $x$. As an assignment, her students need to find the minimum positive integer $y$, which satisfies the following two conditions:
$$x\ \texttt{and}\ y > 0$$ $$x\ \texttt{xor}\ y > 0$$
Where $\texttt{and}$ is the bitwise AND operation, and $\texttt{xor}$ is the bitwise XOR operation.
Among the students was Mystia, who was truly baffled by all these new operators. Please help her!
The first line of input contains a single integer $t$ ($1 \leq t \leq 10^3$) — the number of input test cases.
For each test case, the only line of input contains one integer $x$ ($1 \leq x \leq 2^{30}$).
For each test case, print a single integer — the minimum number of $y$.
Input
The first line of input contains a single integer $t$ ($1 \leq t \leq 10^3$) — the number of input test cases.
For each test case, the only line of input contains one integer $x$ ($1 \leq x \leq 2^{30}$).
Output
For each test case, print a single integer — the minimum number of $y$.

Note
Test case 1:
$1\; \texttt{and}\; 3=1>0$, $1\; \texttt{xor}\; 3=2>0$.
Test case 2:
$2\; \texttt{and}\; 3=2>0$, $2\; \texttt{xor}\; 3=1>0$.
