I'd be very curious to know what the rails code looked like.
They basically ended up with something very similar to what I did, but I
don't have their code. They said it was like this:
look at a line and store the ID in a variable
look at that line + 1
if the ID is the same, keep going
if the ID is different, look at line + 2
if line+2 is the old ID, then line+1 is out of order
if line+2 is the same as line+1, it's a new block
put the new ID into the stored variable
That was what I ended up with too for sequencing checks. Then they said
something about "automatic duplicate checking" which Rails has and we
don't. I had enough repeat loops to make me dizzy. Your one-pass script
was better.
The unique requirement on the type might be (assuming the data has
been processed to 6-item comma-delimited lines):
put the indexes of lines of myList where the count of item 4 of each
> 1 into myDupedTypes
For the requirement across the ID, section, and subsection, and type,
not counting the type when it dupes its parent subsection, maybe:
put the indexes of lines of myList where item 1 of each is among the
items of item 2 to 4 of any into myDupedIDs
I asked a while back if I could just lift out the keys of sub-arrays
from a big array without looping through them all, but nope. Your
suggestions would have been useful too.
