standard outputAnton goes to school, his favorite lessons are arraystudying. He usually solves all the tasks pretty fast, but this time the teacher gave him a complicated one: given two arrays *b* and *c* of length *n*, find array *a*, such that:

where *a* *and* *b* means bitwise AND, while *a* *or* *b* means bitwise OR.

Usually Anton is good in arraystudying, but this problem is too hard, so Anton asks you to help.

Input

The first line of the input contains a single integers *n* (1 ≤ *n* ≤ 200 000) — the size of arrays *b* and *c*.

The second line contains *n* integers *b*_{i} (0 ≤ *b*_{i} ≤ 10^{9}) — elements of the array *b*.

Third line contains *n* integers *c*_{i} (0 ≤ *c*_{i} ≤ 10^{9}) — elements of the array *c*.

Output

If there is no solution, print - 1.

Otherwise, the only line of the output should contain *n* non-negative integers *a*_{i} — elements of the array *a*. If there are multiple possible solutions, you may print any of them.
