Problem Description
Little a has come to college and majored in computer and science.

Today he's learned bit-operations in algorithm lessons, and he got a problem homework.

Here's the problem:

A query only contains a positive integer p, which means you
Are asked to answer the _ result of bit-operations ( and, or, xor ) of all the

There are no more than 15 test cases.

Each test case begins with two positive integers n and p
In a line, indicate the number of and the number of.

2≤n, q≤105.

For each query three non-negative indicates the

Sample Input
3 3
1 1 1

Sample Output
1 1 0
1 1 0
1 1 0
