The box the rays P36035

Your task is to write a program that, given three naturals $n$, $m$ 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 $\backslash$ (to write that character in C or C++, you should write "$\backslash\backslash$").

Input

The input consists of three naturals $n$, $m$ 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 $n\times m$ of asterisks. It must print a line in white after every solution. It can print the solution in any order.
