The diamond kata takes as its input a letter, and outputs it in a diamond shape. Given a letter, it prints a diamond starting with 'A', with the supplied letter at the widest point.
In the following examples, spaces are indicated by 路
characters.
Diamond for letter 'A':
A
Diamond for letter 'C':
路路A路路
路B路B路
C路路路C
路B路B路
路路A路路
Diamond for letter 'E':
路路路路A路路路路
路路路B路B路路路
路路C路路路C路路
路D路路路路路D路
E路路路路路路路E
路D路路路路路D路
路路C路路路C路路
路路路B路B路路路

Output the diamond as a null-terminated string, with a newline character at the end of each row.
An example output would be " A \n B B \nC C\n B B \n A \n"
