For the Diamond exercise in F#, the submission below fails with an empty error message, stating only "We received the following error when we ran your code", but no actual reason.
Looking at the dev console in my browser, I see multiple calls to the "test_run_ endpoint returning
with status 304. If I modify my submission slightly by defining
let space = '.' // instead of let space = ' '
then I receive a "test_run" response with status 200 and some expected test failure messages (after some empty 304s as above).
The code submission:
module Diamond
let alphabet = [|'A'..'Z'|]
let space = ' '
let createUpperHalfRow row size =
let center = size / 2
if row = 0 then
Array.init size (fun i -> if i = center then alphabet.[row] else space)
else
Array.init size (fun i -> if i = center - row || i = center + row then alphabet.[row] else space)
let createUpperHalf size =
Array.init (size / 2 + 1) (fun i -> createUpperHalfRow i size)
let mirrorLowerHalf upperHalf =
let length = Array.length upperHalf
Array.init (length - 1) (fun i -> upperHalf.[length - i - 2])
let make letter =
let size = (Array.findIndex ((=) letter) alphabet) * 2 + 1
let upperHalf = createUpperHalf size
let lowerHalf = mirrorLowerHalf upperHalf
lowerHalf
|> Array.append upperHalf
|> Array.map System.String
|> String.concat System.Environment.NewLine
