Swap Two Numbers Without Using a Third Variable

Your task is to swap two given numbers without utilizing an additional variable and print the swapped values.

Input:

The first line contains an integer 't', indicating the number of test cases.
The following lines each contain two integers 'a' and 'b'.

Output:

For each test case, output the swapped values of 'a' and 'b' as a single line.

Example:

Input:
2
3 7
10 5
Output:
7 3
5 10

Constraints:

  • 1 <= 't' <= 100
  • -105 <= 'a', 'b' <= 105
