write a go solution for Description:
This is an interactive problem. Remember to flush your output while communicating with the testing program. You may use fflush(stdout) in C++, system.out.flush() in Java, stdout.flush() in Python or flush(output) in Pascal to flush the output. If you use some other programming language, consult its documentation. You may also refer to the guide on interactive problems: https://codeforces.com/blog/entry/45307.

The jury picked an integer x not less than 0 and not greater than 2^14-1. You have to guess this integer.

To do so, you may ask no more than 2 queries. Each query should consist of 100 integer numbers a_1, a_2, ..., a_100 (each integer should be not less than 0 and not greater than 2^14-1). In response to your query, the jury will pick one integer i (1<=i<=100) and tell you the value of a_ioplusx (the bitwise XOR of a_i and x). There is an additional constraint on the queries: all 200 integers you use in the queries should be distinct.

It is guaranteed that the value of x is fixed beforehand in each test, but the choice of i in every query may depend on the integers you send.

Input Format:
None

Output Format:
To give the answer, your program should print one line ! x with a line break in the end. After that, it should flush the output and terminate gracefully.

Note:
The example of interaction is not correct — you should sumbit exactly 100 integers in each query. Everything else is correct.
