Nicholas Hathaway, a young programmer, always wanted to be a part of a hacking group, named fsociety and he is fortunate to find that fsociety is currently accepting more members but, this is not a simple task. He had to pass a challenge to become a member of fsociety. The challenge is to encrypt a string using modified ROT13 algorithm.

ROT13 is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. Similiarly for any ROTn each letter of string is replaced by the letter n letters after it.

In modified ROT13, you have to apply ROT13 on each letter of string. If any letter repeats in the given string, then for that letter, use higher ROT i.e. on the second occurrence use ROT14 then ROT15 and so on. So for kth occurrence of any letter use ROTn , where n = (13 + k - 1).
NOTE: n should not be more than 26 so after ROT26, apply ROT1.

Input Format:
The first line of the input contains an integer T, denoting the number of test cases.
Each test case contains a string comprising of only small characters i.e., [a-z].

Output Format:
For each test case, output the modified string followed by a newline.

Constraints:
1 ≤ T ≤ 100
1 ≤ Length of string ≤ 1000

SAMPLE INPUT
2
livethecode
codeemblaze
SAMPLE OUTPUT
yvirguspbqt
pbqrszoynmt
Explanation

Sample Test Case 1:
Letters l, i, v, e, t and h are occurring for the first time so apply ROT13 on them. Next letter e occurred second time so apply ROT14 on it. Now, next letters o and d are occurring for the first time so apply ROT13 on them. Next letter e occurred third time, so apply ROT15 on it. Therefore, output is yvirguspbqt.

Sample Test Case 2:
Similarly, output is pbqrszoynmt.
