12185. Character Patterns (Act 5)
Problem code: CPTTRN5

Using two characters: . (dot) and * (asterisk) print a gridlike pattern.
The grid will have l lines, c columns, and each square shaped element of the grid will have the height and width equal to s.
Moreover, each of the grid elements will have a diagonal. The diagonal of the first square in the first line of the grid is directed towards down and right corner  use the \ (backslash) character to print it; while the next diagonal will be directed towards upper right corner  use the / (slash) character to print it. Print the successive diagonals alternately (please consult the example below).
Input
You are given t  the number of test cases
and for each of the test case three positive integers: l  the number of lines, c  the number of columns in the grid and s  the size of the single square shaped element.
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.
