Day 5 Notes
|
||||||
|
|
||||||
|
+--------+
|
||||||
|
| Part 1 |
|
||||||
|
+--------+
|
||||||
|

||||||

Thoughts:
|
||||||
|
Could do something clever with binaries or the Bitwise module?
|
||||||
|
The number of rows is even (128), but we're zero-indexed (0-127), so how to deal with calculating half?
|
||||||
|
- in binary, can just shift one bit. But again, we need to halve a range (e.g. 32 to 63) so not sure
|
||||||
|
how to do that.
|
||||||
|
|
||||||
|
Instead of storing the range, I decided to store the current "front" seat, and how many rows back to count.
|
||||||
|
Then we can work with 128 which divides by two without worrying about rounding problems.
|
||||||
|
|
||||||
|
When there are only two seats left, just return the correct one based on the flag.
|
||||||
|
|
||||||
|

|
||||||
|
| Part 2 |
|
||||||
|

|
||||||
|
|
||||||

$ elixir day5part2.exs

Thoughts:
|
||||||
|
|
||||||
|
Not really sure what the missing front/back seats was about. Decided just to just compare the sorted list
|
||||||
|
with itself shifted by one (by zipping them), and finding the first ID without a next ID, and assume
|
||||||
|
the next ID is my seat.
|
||||||
|
That turned out to be the right answer.
|
||||||
|
|
||||||
|
|
||||||
|
+------------------+
|
||||||
|
| Overall Thoughts |
|
||||||
|
+------------------+
|
||||||
|
|
||||||
|
Looking forward to seeing how others implemented the seat ID parsing.
|
||||||
|
Did a lot of refactoring here but the end result, especially for part 2, is pretty clean I think.
|
||||||
|
Even if I decided to refactor the parser, it can just be swapped in for part 2. Zipping was a nice idea.
|
||||||
|
|
||||||
|
I quite enjoyed this one, maybe because it's a Saturday and I wasn't burnt out from work :-)
