I must be missing something obvious in 6a. It doesn't look that difficult, but I'm not getting the right answer. My code seems to work for small data sets, but fails for the full problem set.
Off by one error somewhere?

Maybe, but I can't see where.

Would someone who's done 6a like to try it with my data set and let me know what you get? Here's the set:

Does that mean you spotted the reason why you were not getting the correct result? One of the difficult aspects of that particular challenge is that is a hard one to debug.

It was thanks for trying my data with your solution  :)

I have found the reason why my code didn't work. It was because it extracted strings rather than numbers for the coordinates from the instructions  :facepalm: One day I will learn  ::-)

Python on an aging mac. It took a little while, probably my fault for writing stupidly inefficient code. (Couple of minutes? - didn't matter as I was half way through a rather tedious exam invigilation).

You could do it with a stream parser, though I tried it and my code didn't work so reverted to a json parser and a recursive tree walker function to do the addition.
Did you write code for 11? I started to think about how I would code it but had solved it by inspection before I worked out how I would code it.

I've just done days one and two in a spreadsheet. Not gonna work for day 3.


So can anyone suggest a mac based easy to setup and use programming environment. I used to do C a long time ago. Not worried about (re)learning to code, but could do without the pain of learning a clunky environment.

Something with instant feedback would be good. Along the lines of

Print "Hello World"
Run
Hello World

Would be great :-)

http://processing.org

It's based on Java, so shares a C like syntax, but with a lower barrier to entry. I've used it to answer the first 12 days' advent questions so far.

println("hello world!");

works straight out of the box.

Loading text files is easy (loadStrings()), as is conversion to character arrays (.toCharArray()) and regular expressions, all of which are helpful for the challenge.

@tonycollinet: from a background of non-coder scared of incomprehensible IDEs, I'm using perl that I found was already on my computer. I just use an ascii text editor to write code, save it, then use perl to compile and run. I think Macs have perl onboard by default. Type perl -v to find version.

I completed day 7 last night.  It took me a lot longer than I'd anticipated.

I've skipped day 7* and done day 8.

processing.org seems to fit the bill

Thanks jo.

Will play after my trip to Germany.


(Thanks also Pancho for the perl suggestion.)

Did you write code for 11? I started to think about how I would code it but had solved it by inspection before I worked out how I would code it.

I can see the answer to my day 11, also by inspection.  I wrote code but it is still running, though, despite applying some optimisations:-

as an aside, I've been using this as an excuse to start playing around in test-driven development using the Python unittest framework

Code: [Select]
class TestIt(unittest.TestCase):
    # Part 1 tests
       
    def test_01(self):
        self.assertEqual(incr('aa'), 'ab')
 
    def test_02(self):
        self.assertEqual(incr('az'), 'ba')
 
    def test_03(self):
        self.assertEqual(incr('zz'), 'aaa') # my own assumption - not mentioned in TEH RULZ

    def test_04(self):
        self.assertFalse(pwOK('hijklmmn'))

    def test_05(self):
        self.assertFalse(pwOK('abbceffg'))

    def test_06(self):
        self.assertFalse(pwOK('abbcegjk'))

    def test_07(self):
        self.assertTrue(pwOK('abcdffaa'))

    def test_08(self):
        self.assertTrue(pwOK('ghjaabcc'))

(I've hidden some tests as they give a clue to some of the stuff I mention in the spoiler above):-

Re: my Day 11 woes...

As an alternative to looking for optimisations,  I could always just fix the bug that had it spinning in a tight loop going nowhere  :facepalm:

runs in under a second now  ::-)

I am an idiot!
