## \-\-- Day 7: Recursive Circus \-\--
|
||||
|
||||
Wandering further through the circuits of the computer, you come upon a
|
||||
tower of programs that have gotten
|
||||
themselves into a bit of trouble. A recursive algorithm has gotten out
|
||||
of hand, and now they\'re balanced precariously in a large tower.
|
||||
|
||||
One program at the bottom supports the entire tower. It\'s holding a
|
||||
large disc, and on the disc are balanced several more sub-towers. At the
|
||||
bottom of these sub-towers, standing on the bottom disc, are other
|
||||
programs, each holding *their* own disc, and so on. At the very tops of
|
||||
these sub-sub-sub-\...-towers, many programs stand simply keeping the
|
||||
disc below them balanced but with no disc of their own.
|
||||
|
||||
You offer to help, but first you need to understand the structure of
|
||||
these towers. You ask each program to yell out their *name*, their
|
||||
*weight*, and (if they\'re holding a disc) the *names of the programs
|
||||
immediately above them* balancing on that disc. You write this
|
||||
information down (your puzzle input). Unfortunately, in their panic,
|
||||
they don\'t do this in an orderly fashion; by the time you\'re done,
|
||||
you\'re not sure which program gave which information.
|
||||
|
||||
For example, if your list is the following:
|
||||
|
||||
pbga (66)
|
||||
xhth (57)
|
||||
ebii (61)
|
||||
havc (66)
|
||||
ktlj (57)
|
||||
fwft (72) -> ktlj, cntj, xhth
|
||||
qoyq (66)
|
||||
padx (45) -> pbga, havc, qoyq
|
||||
tknk (41) -> ugml, padx, fwft
|
||||
jptl (61)
|
||||
ugml (68) -> gyxo, ebii, jptl
|
||||
gyxo (61)
|
||||
cntj (57)
|
||||
|
||||
\...then you would be able to recreate the structure of the towers that
|
||||
looks like this:
|
||||
|
||||
gyxo
|
||||
/
|
||||
ugml - ebii
|
||||
/ \
|
||||
| jptl
|
||||
|
|
||||
| pbga
|
||||
/ /
|
||||
tknk --- padx - havc
|
||||
\ \
|
||||
| qoyq
|
||||
|
|
||||
| ktlj
|
||||
\ /
|
||||
fwft - cntj
|
||||
\
|
||||
xhth
|
||||
|
||||
In this example, `tknk` is at the bottom of the tower (the *bottom
|
||||
program*), and is holding up `ugml`, `padx`, and `fwft`. Those programs
|
||||
are, in turn, holding up other programs; in this example, none of those
|
||||
programs are holding up any other programs, and are all the tops of
|
||||
their own towers. (The actual tower balancing in front of you is much
|
||||
larger.)
|
||||
|
||||
Before you\'re ready to help them, you need to make sure your
|
||||
information is correct. *What is the name of the bottom program?*
|
||||
|
||||
To begin, [get your puzzle input](7/input).
