A faulty wire means Nusrat can't use a temporary register when swapping two sensor values — she must swap them using pure XOR tricks. Read two integers A and B, swap their values using XOR (no temporary variable), and print them in swapped order.
Input
Two integers A B.
Output
B and A (swapped), space-separated.
Constraints
0 ≤ A,B ≤ 10^9
Sample Input
5 9
Sample Output
9 5
