CPTTRN2 - Character Patterns (Act 2)


Using two characters: . (dot) and * (asterisk) print a frame-like pattern.

Input

You are given t - the number of test cases and for each of the test cases two positive integers: l - the number of lines and c - the number of columns of a frame.

Output

For each of the test cases output the requested pattern (please have a look at the example). Use one line break in between successive patterns.

Example

Input:
3
3 1
4 4
2 5

Output:
*
*
*

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

hint: listen to instruction on output, there needs in fact to be one free newline between cases, the example output is wrong. Test for extremely small numbers, where no dot would fit in the frame.
