The box of the rays

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 × m. A ray is a vertical sequence of diagonals to the left / or to the
right ∖ (to write that character in C or C++, you should write "∖∖").

Input

The input consists of three naturals n, m and c, with n > 0, m > 0 and
0 ≤ c ≤ m.

Output

Your program must print all the possible rays with the beginning in the
columns c in a box n × m of asterisks. It must print a line in white
after every solution. It can print the solution in any order.
