You have a string $s$ consisting of digits from $0$ to $9$ inclusive. You can perform the following operation any (possibly zero) number of times:
- You can choose a position
$i$and delete a digit$d$on the$i$-th position. Then insert the digit$\min{(d + 1, 9)}$on any position (at the beginning, at the end or in between any two adjacent digits).
What is the lexicographically smallest string you can get by performing these operations?
A string $a$ is lexicographically smaller than a string $b$ of the same length if and only if the following holds:
- in the first position where
$a$and$b$differ, the string$a$has a smaller digit than the corresponding digit in$b$.
Input
The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases. Then the test cases follow.
Each test case consists of a single line that contains one string $s$ ($1 \le |s| \le 2 \cdot 10^5$) — the string consisting of digits. Please note that $s$ is just a string consisting of digits, so leading zeros are allowed.
It is guaranteed that the sum of lengths of $s$ over all test cases does not exceed $2 \cdot 10^5$.
Output
Print a single string — the minimum string that is possible to obtain.
Note
In the first test case:
- Delete
$8$and insert$9$at the end of the notation. The resulting notation is$04299$. - Delete
$4$and insert$5$in the$3$-rd position of the notation. The resulting notation is$02599$.
Nothing needs to be done in the second and third test cases.
