Given a word w, rearrange the letters of w to construct another word s in such a way that s is lexicographic-ally greater than w. In case of multiple possible answers, find the lexicographic-ally smallest one.

Input Format

The first line of input contains t, the number of test cases. Each of the next t lines contains w.

Output Format

For each testcase, output a string lexicographically bigger than w in a separate line. In case of multiple possible answers, print the lexicographically smallest one, and if no answer exists, print no answer.

Constraints

1≤t≤105

1≤|w|≤100

w will contain only lower-case English letters and its length will not exceed 100.

SAMPLE INPUT
5
ab
bb
hefg
dhck
dkhc

SAMPLE OUTPUT
ba
no answer
hegf
dhkc
hcdk

Explanation

Test case 1:

There exists only one string greater than 'ab' which can be built by   rearranging  'ab'. That is 'ba'.

**Test case 2:**

Not possible to rearrange 'bb' and get a lexicographically greater string.

**Test case 3:**

'hegf' is the next string lexicographically greater than 'hefg'.

**Test case 4:**

'dhkc' is the next string lexicographically greater than 'dhck'.

**Test case 5:**

'hcdk' is the next string lexicographically greater than 'dkhc'.
