This is an easy version of the problem. The only difference between an easy and a hard version is the constraints on $$$a$$$, $$$b$$$, $$$c$$$ and $$$d$$$.
You are given $$$4$$$ positive integers $$$a$$$, $$$b$$$, $$$c$$$, $$$d$$$ with $$$a < c$$$ and $$$b < d$$$. Find any pair of numbers $$$x$$$ and $$$y$$$ that satisfies the following conditions:
Note that required $$$x$$$ and $$$y$$$ may not exist.
The first line of the input contains a single integer $$$t$$$ $$$(1 \leq t \leq 10$$$), the number of test cases.
The descriptions of the test cases follow.
The only line of each test case contains four integers $$$a$$$, $$$b$$$, $$$c$$$ and $$$d$$$ ($$$1 \leq a < c \leq 10^5$$$, $$$1 \leq b < d \leq 10^5$$$).
For each test case print a pair of numbers $$$a < x \leq c$$$ and $$$b < y \leq d$$$ such that $$$x \cdot y$$$ is divisible by $$$a \cdot b$$$. If there are multiple answers, print any of them. If there is no such pair of numbers, then print -1 -1.
