CPTTRN7 - Character Patterns (Act 7)

Print a regular grid pattern with diamond-like base elements. Use the \ (backslash) and the / (slash) characters to print diamonds and . (dots) to fill the rest of the space.

Input

You are given t - the number of test cases and for each of the test cases three positive integers: r - the number of rows, c - the number of columns in the grid and s - the size of each diamond.

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 2 
4 4 1 
2 5 2

Output:
