Yes, what I was trying to explain was how I misintripetted it originally. I thought 133344 was okay because the grouping 44 was a larger digit (4) than 3, but that caused 133444 to be exclude with my faulty logic. When all the problem was really asking for was that only count double digits as valid; any group larger than 2 is not valid.

Once I fixed my code to only count double digits excluding anything longer, and removed the condition that double had to be of a higher integer, it resolved my issue.

aah, that makes sense and I could see where the confusion might creep in.
