题目描述

This is an easy version of the problem. The only difference between an easy and a hard version is the constraints on aa , bb , cc and dd .

You are given 44 positive integers aa , bb , cc , dd with a<ca < c and b<db < d . Find any pair of numbers xx and yy that satisfies the following conditions:

  • a<xca < x \leq c , b<ydb < y \leq d ,
  • xyx \cdot y is divisible by aba \cdot b .

Note that required xx and yy may not exist.

输入格式

The first line of the input contains a single integer tt (1t10(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 aa , bb , cc and dd ( 1a<c1051 \leq a < c \leq 10^5 , 1b<d1051 \leq b < d \leq 10^5 ).

输出格式

For each test case print a pair of numbers a<xca < x \leq c and b<ydb < y \leq d such that xyx \cdot y is divisible by aba \cdot b . If there are multiple answers, print any of them. If there is no such pair of numbers, then print -1 -1.
