— Perfect Memento in Strict Sense

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!

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 $$$y$$$.

Sample Input:

Sample Output:

Note:

Test case 1:

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

Test case 2:

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