CF 453A . Little Pony and Crystal Mine

这题是C语言练习题吧=。=，做的时候还bug半天，被自己蠢哭了

Twilight Sparkle once got a crystal from the Crystal Mine. A crystal of size n (n is
odd; n > 1) is an n × n matrix with a diamond
inscribed into it.

You are given an odd integer n. You need to draw a crystal of size n.
The diamond cells of the matrix should be represented by character "D". All other cells of the matrix should be represented by character "*".
Look at the examples to understand what you need to draw.

Input

The only line contains an integer n (3 ≤ n ≤ 101; n is
odd).

Output

Output a crystal of size n.
