Given a character from the alphabet, print a diamond of its output with that character being the midpoint of the diamond.

Examples

> diamond.exe A
  A

> diamond.exe B
   A
  B B
   A

> diamond.exe C
    A
   B B
  C   C
   B B
    A

It may be helpful visualise the whitespace in your rendering like this:

> diamond.exe C
_ _ A _ _
_ B _ B _
C _ _ _ C
_ B _ B _
_ _ A _ _
