It turns out that my toaster is a tad broken. It lost WiFi (You know, it's one of those newfangled smart toasters), and its been going bonkers! Since it no longer works, I've been having to hack into my breakfast's source code and run Plate.bread.toastAs(3); every morning. Will you help?

My toaster takes one input: the amount of time you want to toast your bread. This is written as min:sec, such as 5:45 or 0:40 (Up to 59:59). It then returns a specific value for different levels of toastiness:

0:00-0:30 = Bread
0:31-1:00 = Warm Bread
1:01-2:00 = Toasty
2:01-3:30 = Burnt
3:31 and up = Brûlée (or Brulee)

But here's the catch: my toaster has a broken keyboard! Your code can't contain any semicolons or...colons. This might be harder than the toaster repairman said it would be...

Here are some test cases, so you can...test your cases?

0:00 = Bread
5:50 = Brulee or Brûlée
2:00 = Toasty
ChicknMcNuggets = Anything
-1:00 = Anything
0:60 = Anything
1 = Anything
60:00 = Anything
1:00:00 = Anything

    Shouldn't it be 3:31 and up: Brulee? – Mego Nov 3 at 4:17

-6 with thanks to @tsh and also thanks for tho TIO test cases.

-2 with a couple of cool tips from @BlackOwlKai

Throws a ValueError for invalid inputs that cannot be converted to a float. For numbers less than 0 it returns "Bread" because it is still bread. Guess if we are really strict on ensuring that the input is a valid time it could be done but for me the interesting bit was how to avoid the : in Python.

Did you know that SQL can't natively split strings in any decent capacity? Don't let STRING_SPLIT fool you; it doesn't work for this. Or at least, I'm not smart enough to figure it out.

Different from BradC's table-based T-SQL solution.


-- Input variable
DECLARE @i varchar(9)

-- Time declarations (passes in as form "00:mm:ss")
-- CHAR(58) maps to ':'
DECLARE @a time = '0' + CHAR(58) + @i

-- Integer declarations
DECLARE @ int = DATEPART(N, @a),    -- minutes
        @s int = DATEPART(S, @a)    -- seconds

            WHEN @ < 1 AND @x < 31              -- 0:00 - 0:30
                THEN 'Bread'
            WHEN @ < 1 OR @ = 1 AND @x = 0      -- 0:31 - 1:00
                THEN 'Warm Bread'
            WHEN @ < 2 OR @ = 2 AND @x = 0      -- 1:01 - 2:00
                THEN 'Toasty'
            WHEN @ < 3 OR @ < 4 AND @x < 31     -- 2:01 - 3:30
                THEN 'Burnt'
            ELSE 'Brulee'                       -- 3:31 - 59:59

-- Setting input as a time means that you only have to check if the seconds input is two characters, all other checks accounted for
WHERE LEN(RIGHT(@i, LEN(@i) - CHARINDEX(CHAR(58), @i))) = 2
  • You could do something like SELECT value FROM STRING_SPLIT(@i,CHAR(58)), although I'm wondering if a TRY_CAST(@i AS TIME) might cut some corners. – BradC Nov 8 at 22:48
  • Interesting language for golfing! – Redwolf Programs Nov 9 at 2:17
  • @BradC I tried doing STRING_SPLIT like that, but it doesn't exactly work as you'd think - it actually returns both values from each side simultaneously, and you can't do any checks on the data (at least that I could figure out). As for using TRY_CAST, it looks like it would require having "00:" appended to the front. I might be able to work further with that. – Meerkat Nov 9 at 14:15
  • 1
    Yeah, STRING_SPLIT returns them as separate rows. Even without changing those parts, you can still save a ton of bytes by keeping only your very first DECLARE and changing the rest to commas. Also drop AS and just do DECLARE @i varchar(99),@a varchar(9)=... – BradC Nov 9 at 14:31
  • Yeah, good call. Since @a and @b both require @i though, I have to declare that separately. Can still save quite a few bytes there though. – Meerkat Nov 9 at 14:35

T-SQL, 143 155 bytes

(VALUES(31,'Bread'),(61,'Warm Bread'),(121,'Toasty'),(211,'Burnt'),(1E4,'Brulee'))t(a,b)

Line breaks are for readability only. Different method than Meerkat's variable-based SQL solution.

Input is taken via pre-existing table i with varchar field v, per our IO standards. That input table is cross-joined to an in-memory table t with our cutoff values (in seconds) and the desired labels.

The magic happens in the WHERE clause: DATEDIFF calculates the difference in seconds between midnight and our input (with an extra 0: attached to the front), then returns the lowest matching label (via the TOP 1 and ORDER BY).

Invalid inputs either return an unpredictable value or throw an error:
Conversion failed when converting date and/or time from character string.

The question was a little vague, but if needed I can avoid these errors (and return nothing) by adding a LIKE pattern to the WHERE clause, bringing the total bytes to 238 211:

(VALUES(31,'Bread'),(61,'Warm Bread'),(121,'Toasty'),(211,'Burnt'),(1E4,'Brulee'))t(a,b)
WHERE a>DATEDIFF(s,0,'0'+CHAR(58)+v)
AND RIGHT('0'+v,5)LIKE'[0-5][0-9]'+CHAR(58)+'[0-5][0-9]'

EDIT: My original shorter submission was failing for inputs over 24:00, since I was treating it as hh:mm. Had to add the '0'+CHAR(58)+ prefix, which added 12 bytes.

EDIT 2: Shaved 27 bytes from the LIKE in my alternate version

Gotta use those unicode escape sequences :-) just a big chain of ternary operators, with variables defined by default parameters. Also a one-liner, so no semicolon-hungry js
