Twilight Sparkle once got a crystal from the Crystal Mine. A crystal of size n (n is odd; n \gt 1) is an n \times 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.
The only line contains an integer n (3 \le n \le 101; n is odd).
Output a crystal of size n.
