Swap Two Numbers Problem Statement

Given two integers a and b, your task is to swap these numbers and output the swapped values.

Input:

The first line contains a single integer 't', representing the number of test cases.
Each subsequent line contains two space-separated integers, 'a' and 'b'. 

Output:

For each test case, output the swapped values in a single line as 'b' followed by 'a'.

Example:

Input:
2
3 4
5 6
Output:
4 3
6 5

Constraints:

• 1 <= 't' <= 10²
• -10⁵ <= 'a', 'b' <= 10⁵
• Time Limit: 1 sec

Note:

You do not need to print anything; it has already been taken care of. Just implement the specified function to return the results.
