Instructions

Complete the function "make_diamond" that takes a letter as input, and outputs it in a diamond shape.

Rules:

  • The first and last row contain one 'A'.
  • The given letter has to be at the widest point.
  • All rows, except the first and last, have exactly two identical letters.
  • All rows have as many trailing spaces as leading spaces. (This might be 0).
  • The diamond is vertically and horizontally symmetric.
  • The diamond width equals the height.
  • The top half has the letters in ascending order. (abcd)
  • The bottom half has the letters in descending order. (dcba)
