# Diamond
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.
## Requirements
* The first row contains one 'A'.
* The last row contains one 'A'.
* 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 horizontally symmetric.
* The diamond is vertically symmetric.
* The diamond has a square shape (width equals height).
* The letters form a diamond shape.
* The top half has the letters in ascending order.
* The bottom half has the letters in descending order.
* The four corners (containing the spaces) are triangles.
## Examples
In the following examples, spaces are indicated by `·` characters.
Diamond for letter 'A':
```plain
A
```
Diamond for letter 'C':
```plain
··A··
·B·B·
C···C
·B·B·
··A··
```
Diamond for letter 'E':
```plain
····A····
···B·B···
··C···C··
·D·····D·
E·······E
·D·····D·
··C···C··
···B·B···
····A····
```
## Running the tests
To run the tests run the command `go test` from within the exercise directory.
If the test suite contains benchmarks, you can run these with the `-bench`
flag:
go test -bench .
Keep in mind that each reviewer will run benchmarks on a different machine, with
different specs, so the results from these benchmark tests may vary.
