## diamond_creation
|
||
|
|
||
|
### 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)
|
||
|
