--- Day 7: Some Assembly Required ---
|
||||
This year, Santa brought little Bobby Tables a set of wires and bitwise logic gates! Unfortunately, little Bobby is a little under the recommended age range, and he needs help assembling the circuit.
|
||||
|
||||
Each wire has an identifier (some lowercase letters) and can carry a 16-bit signal (a number from 0 to 65535). A signal is provided to each wire by a gate, another wire, or some specific value. Each wire can only get a signal from one source, but can provide its signal to multiple destinations. A gate provides no signal until all of its inputs have a signal.
|
||||
|
||||
The included instructions booklet describes how to connect the parts together: x AND y -> z means to connect wires x and y to an AND gate, and then connect its output to wire z.
|
||||
|
||||
For example:
|
||||
|
||||
123 -> x means that the signal 123 is provided to wire x.
|
||||
x AND y -> z means that the bitwise AND of wire x and wire y is provided to wire z.
|
||||
p LSHIFT 2 -> q means that the value from wire p is left-shifted by 2 and then provided to wire q.
|
||||
NOT e -> f means that the bitwise complement of the value from wire e is provided to wire f.
|
||||
Other possible gates include OR (bitwise OR) and RSHIFT (right-shift). If, for some reason, you'd like to emulate the circuit instead, almost all programming languages (for example, C, JavaScript, or Python) provide operators for these gates.
|
||||
|
||||
For example, here is a simple circuit:
|
||||
|
||||
123 -> x
|
||||
456 -> y
|
||||
x AND y -> d
|
||||
x OR y -> e
|
||||
x LSHIFT 2 -> f
|
||||
y RSHIFT 2 -> g
|
||||
NOT x -> h
|
||||
NOT y -> i
|
||||
After it is run, these are the signals on the wires:
|
||||
|
||||
d: 72
|
||||
e: 507
|
||||
f: 492
|
||||
g: 114
|
||||
h: 65412
|
||||
i: 65079
|
||||
x: 123
|
||||
y: 456
|
||||
In little Bobby's kit's instructions booklet (provided as your puzzle input), what signal is ultimately provided to wire a?
|
||||
|
||||
Your puzzle answer was 46065.
|
||||
|
||||
--- Part Two ---
|
||||
Now, take the signal you got on wire a, override wire b to that signal, and reset the other wires (including wire a). What new signal is ultimately provided to wire a?
|
||||
|
||||
Your puzzle answer was 14134.
|
||||
|
||||
Both parts of this puzzle are complete! They provide two gold stars: **
