AHK Education, the educational program section of Aizu Broadcasting Cooperation, broadcasts a children’s workshop program called "Let's Play and Make." Today’s theme is "Make your own flag." A child writes his first initial in the center of their rectangular flag.
Given the flag size and the initial letter to be placed in the center of it, write a program to draw the flag as shown in the figure below.
+-------+ |.......| |...A...| |.......| +-------+
The figure has "A" in the center of a flag with size 9 (horizontal) × 5 (vertical).
The input is given in the following format.
W H c
The input line provides the flag dimensions W (width) and H (height) (3 ≤ W,H ≤ 21), and the initial letter c. Both W and H are odd numbers, and c is a capital letter.
Draw the flag of specified size with the initial in its center using the following characters: "+" for the four corners of the flag, "-" for horizontal lines, "|" for vertical lines, and "." for the background (except for the initial in the center).
