SPTTRN4 - Straight Line Spiral Pattern (Act 4)

For this problem we consider spirals drawn as ASCII Art pictures using only the * and . character in an s by s grid. We call s the size of the spiral. Here are example of such spirals for some values of s.

The spiral of size s=3

*.*
*.*
***

The spiral of size s=4

*.**
*..*
*..*
****

The spiral of size s=5

*.***
*.*.*
*.*.*

The spiral of size s=6

Input

The first line contains an integer T=1000, which is the number of test cases. Then the next T lines contain 3 integers separated by a single space, namely 3≤s≤10000, 1≤i≤s and 1≤j≤s.

Output

For each test case output in a single line the character of the spiral of size s at row i and at column j.

Example

Input:
3
3 1 1
4 3 2
5 2 3 Output: *
.
*
