题目描述

Monocarp is a great solver of adhoc problems. Recently, he participated in an Educational Codeforces Round, and gained rating!

Monocarp knew that, before the round, his rating was aa . After the round, it increased to bb ( b>ab > a ). He wrote both values one after another to not forget them.

However, he wrote them so close to each other, that he can't tell now where the first value ends and the second value starts.

Please, help him find some values aa and bb such that:

  • neither of them has a leading zero;
  • both of them are strictly greater than 00 ;
  • b>ab > a ;
  • they produce the given value abab when written one after another.

If there are multiple answers, you can print any of them.

输入格式

The first line contains a single integer tt ( 1t1041 \le t \le 10^4 ) — the number of testcases.

The only line of each testcase consists of a single string abab of length from 22 to 88 that:

  • consists only of digits;
  • doesn't start with a zero.

输出格式

For each testcase, determine if such values aa and bb exist. If they don't, print -1. Otherwise, print two integers aa and bb .

If there are multiple answers, you can print any of them.

输入输出样例

  • 输入#1

    5
    20002001
    391125
    200200
    2001000
    12

    输出#1

    2000 2001
    39 1125
    -1
    200 1000
    1 2

说明/提示

In the second testcase, printing 33 and 9112591125 is also valid.

In the third testcase, 2020 and 02000200 is not valid, because bb has a leading zero. 200200 and 200200 is not valid, because 200200 is not strictly greater than 200200 .
