Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard outputYou are given two segments $$$[l_1; r_1]$$$ and $$$[l_2; r_2]$$$ on the $$$x$$$-axis. It is guaranteed that $$$l_1 < r_1$$$ and $$$l_2 < r_2$$$. Segments may intersect, overlap or even coincide with each other.

Your problem is to find two integers $$$a$$$ and $$$b$$$ such that $$$l_1 \le a \le r_1$$$, $$$l_2 \le b \le r_2$$$ and $$$a \ne b$$$. In other words, you have to choose two distinct integer points in such a way that the first point belongs to the segment $$$[l_1; r_1]$$$ and the second one belongs to the segment $$$[l_2; r_2]$$$.

It is guaranteed that the answer exists. If there are multiple answers, you can print any of them.

You have to answer $$$q$$$ independent queries.

Input

The first line of the input contains one integer $$$q$$$ ($$$1 \le q \le 500$$$) — the number of queries.

Each of the next $$$q$$$ lines contains four integers $$$l_{1_i}, r_{1_i}, l_{2_i}$$$ and $$$r_{2_i}$$$ ($$$1 \le l_{1_i}, r_{1_i}, l_{2_i}, r_{2_i} \le 10^9, l_{1_i} < r_{1_i}, l_{2_i} < r_{2_i}$$$) — the ends of the segments in the $$$i$$$-th query.

Output

Print $$$2q$$$ integers. For the $$$i$$$-th query print two integers $$$a_i$$$ and $$$b_i$$$ — such numbers that $$$l_{1_i} \le a_i \le r_{1_i}$$$, $$$l_{2_i} \le b_i \le r_{2_i}$$$ and $$$a_i \ne b_i$$$. Queries are numbered in order of the input.

It is guaranteed that the answer exists. If there are multiple answers, you can print any.
