The box of the rays

Write a program that, given three natural numbers $n$ , $m$ and $c$ prints all the possible rays with the beginning in the column $c$ in a box $n\times m$ . A ray is a vertical sequence of diagonals to the left or to the right.

Input

Input consists of three natural numbers $n$ , $m$ and $c$ , with $n > 0$ , $m > 0$ and $0\le c \le m$ .

Output

Your program must print all the possible rays with the beginning in the columns $c$ in a box $n\times m$ . The solutions must appear in the same order than in the instances. It must print asterisks around every solution, and print a line in white after each solution.
