[Newbies] Teaching Smalltalk

[David Mitchell]

Bummed that Why Smalltalk is gone.

Here is my crack at translating. Wouldn't say this is idiomatic Smalltalk
(transliterated C never will be). But it ran in the transcript.

Tried to only use ANSI Smalltalk:

| count doors |
count := 10.
"Initialize the array of doors to 0 (closed)"
doors := (Array new: count) atAllPut:  false.

"Process the doors"
1 to: count do:
    [ :pass |
    pass to: count by: pass do:
        [ :door |
        doors
            at: door
            put: (doors at: door) not ] ].

"Print out the results"
1 to: count do:
    [ :n |
    Transcript
        show: 'door #', n, ' is ';
        show: ((doors at: door) ifTrue: [#open] ifFalse: [#closed]);
        cr]
