Given an odd length word your task is to complete the function printPattern that takes a string s as its argument and prints it from the middle of the word such that it follows the following pattern.

Input: PROGRAM                            Input: RAT
Output:                                   Output:
G                                       A
GR                                      AT
GRA                                     ATR
GRAM
GRAMP
GRAMPR
GRAMPRO

The above is proper shaped pattern for the test case, but when
printed in a single line it becomes as shown in the output.


Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case consists of a single line containing an odd length string s.

Output:
Corresponding to each test case in a new line print the pattern in a  single line where each row of the pattern is separated by a "$" instead of a new line.
