Apples and Ideas Time Limit: 2 Seconds      Memory Limit: 65536 KB

"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 andD 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.

Sample Input

4
0 0 5 30
20 25 20 0
20 25 20 15
20 25 25 30

Sample Output

5 30
0 30
20 25
20 25
20 40
20 40
25 55
20 55

解题思路：

	区分苹果和思维，苹果只能交换，而主意交换只能是不变或是变多。

#include<stdio.h>
#include<string.h>
#include<algorithm>
using namespace std;
int main()
{
	int t;
	scanf("%d",&t);
	while(t--)
	{
		int ap,b,cp,d;
		scanf("%d%d%d%d",&ap,&b,&cp,&d);
		int ans;
		ans=b+d;
		printf("%d %d\n",cp,ans);
		printf("%d %d\n",ap,ans);
	}
	return 0;
}
