Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ACM-ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.

standard inputoutput

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.
