CF1913A.Rating Increase

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 $a$. After the round, it increased to $b$ ($b \gt a$). 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 $a$ and $b$ such that:

• neither of them has a leading zero;
• both of them are strictly greater than $0$;
• $b \gt a$;
• they produce the given value $ab$ when written one after another.

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

Monocarp 是一道“即兴题”（adhoc problem）的高手。最近，他参加了一场 Educational Codeforces Round，并成功提升了评分！

Monocarp 记得，比赛前他的评分为 $a$，赛后提升到了 $b$（其中 $b \gt a$）。他将这两个数值依次写在了一起，以免遗忘。

然而，他把两个数写得过于紧凑，以至于现在无法分辨第一个数在哪里结束、第二个数从哪里开始。

请帮助他找出满足以下条件的某个 $a$ 和 $b$：

• 二者均不以 $0$ 开头（即无前导零）；
• 二者均严格大于 $0$；
• $b \gt a$；
• 将 $a$ 和 $b$ 依次拼接后得到给定的数值 $ab$。

若存在多个解，输出任意一个即可。

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

The only line of each testcase consists of a single string $ab$ of length from $2$ to $8$ that:

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

第一行包含一个整数 $t$（$1 \le t \le 10^4$）—— 表示测试用例的数量。

每个测试用例仅有一行，包含一个长度为 $2$ 到 $8$ 的字符串 $ab$，满足：

• 字符串仅由数字组成；
• 字符串不以零开头。

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

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

对于每个测试用例，判断是否存在满足条件的值 $a$ 和 $b$。若不存在，输出 -1；否则，输出两个整数 $a$ 和 $b$。

若存在多个答案，输出任意一个即可。

In the second testcase, printing $3$ and $91125$ is also valid.

In the third testcase, $20$ and $0200$ is not valid, because $b$ has a leading zero. $200$ and $200$ is not valid, because $200$ is not strictly greater than $200$.

在第二个测试用例中，输出 $3$ 和 $91125$ 也是有效的。

在第三个测试用例中，$20$ 和 $0200$ 是无效的，因为 $b$ 有前导零。$200$ 和 $200$ 是无效的，因为 $200$ 并不严格大于 $200$。
