My orzlers, we can optimize this problem from $$$O(S^3)$$$ to $$$O\left(T^\frac{5}{9}\right)$$$!

— Spyofgame, founder of Orzlim religion

A long time ago, Spyofgame invented the famous array $$$a$$$ ($$$1$$$-indexed) of length $$$n$$$ that contains information about the world and life. After that, he decided to convert it into the matrix $$$b$$$ ($$$0$$$-indexed) of size $$$(n + 1) \times (n + 1)$$$ which contains information about the world, life and beyond.

Spyofgame converted $$$a$$$ into $$$b$$$ with the following rules.

$$$b_{i,0} = 0$$$ if $$$0 \leq i \leq n$$$;
$$$b_{0,i} = a_{i}$$$ if $$$1 \leq i \leq n$$$;
$$$b_{i,j} = b_{i,j-1} \oplus b_{i-1,j}$$$ if $$$1 \leq i, j \leq n$$$.

Here $$$\oplus$$$ denotes the bitwise XOR operation.

Today, archaeologists have discovered the famous matrix $$$b$$$. However, many elements of the matrix has been lost. They only know the values of $$$b_{i,n}$$$ for $$$1 \leq i \leq n$$$ (note that these are some elements of the last column, not the last row).

The archaeologists want to know what a possible array of $$$a$$$ is. Can you help them reconstruct any array that could be $$$a$$$?

Input

The first line contains a single integer $$$n$$$ ($$$1 \leq n \leq 5 \cdot 10^5$$$).

The second line contains $$$n$$$ integers $$$b_{1,n}, b_{2,n}, \ldots, b_{n,n}$$$ ($$$0 \leq b_{i,n} \lt 2^{30}$$$).

Output

If some array $$$a$$$ is consistent with the information, print a line containing $$$n$$$ integers $$$a_1, a_2, \ldots, a_n$$$. If there are multiple solutions, output any.

If such an array does not exist, output $$$-1$$$ instead.

Note

If we let $$$a = [1,2,3]$$$, then $$$b$$$ will be:

$$$\bf{0}$$$	$$$\bf{1}$$$	$$$\bf{2}$$$	$$$\bf{3}$$$
$$$\bf{0}$$$	$$$1$$$	$$$3$$$	$$$0$$$
$$$\bf{0}$$$	$$$1$$$	$$$2$$$	$$$2$$$
$$$\bf{0}$$$	$$$1$$$	$$$3$$$	$$$1$$$

The values of $$$b_{1,n}, b_{2,n}, \ldots, b_{n,n}$$$ generated are $$$[0,2,1]$$$ which is consistent with what the archaeologists have discovered.
