zoj-3936-Apples and Ideas

If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.” - George Bernard Shaw

Now Alice has A apples and B ideas, while Bob has C apples and D ideas, what will they have if they exchange all things?

Input

There are multiple test cases. The first line of input contains an integer T indicating the number of test cases. For each test case:

The only line contains four integers A, B, C, D (0 <= A, B, C, D <= 100) - as the problem described.

Output

For each test case, output two lines. First line contains two integers, indicating the number of Alice’s apples and ideas; second line contains two integers, indicating the number of Bob’s apples and ideas.
