hey Leute,

ka ob ihr schon das hier kennt: Advent of Code

Spaßige Aufgaben passend zur Weihnachtszeit :)

Hänge aber gerade bei Aufgabe 7 (Day7):
Am besten ihr lest euch dazu die aufgabe kurz durch.

EDIT: Hier die Aufgabe:
Code:
[B]--- Day 7: Some Assembly Required ---[/B]

[FONT=Source Code Pro]This year, Santa brought little Bobby Tables a set of wires and[URL="https://en.wikipedia.org/wiki/Bitwise_operation"]bitwise logic gates[/URL]! Unfortunately, little Bobby is a little under the recommended age range, and he needs help assembling the circuit.[/FONT]
[FONT=Source Code Pro]Each wire has an identifier (some lowercase letters) and can carry a [URL="https://en.wikipedia.org/wiki/16-bit"]16-bit[/URL]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.[/FONT]
[FONT=Source Code Pro]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.
[/FONT]
[FONT=Source Code Pro]For example:[/FONT]

[LIST]
[*]123 -> x means that the signal 123 is provided to wire x.
[*]x AND y -> z means that the [URL="https://en.wikipedia.org/wiki/Bitwise_operation#AND"]bitwise AND[/URL] of wire x and wire y is provided to wire z.
[*]p LSHIFT 2 -> q means that the value from wire p is [URL="https://en.wikipedia.org/wiki/Logical_shift"]left-shifted[/URL] by 2and then provided to wire q.
[*]NOT e -> f means that the [URL="https://en.wikipedia.org/wiki/Bitwise_operation#NOT"]bitwise complement[/URL] of the value from wire eis provided to wire f.
[/LIST]



[FONT=Source Code Pro]Other possible gates include OR ([URL="https://en.wikipedia.org/wiki/Bitwise_operation#OR"]bitwise OR[/URL]) and RSHIFT ([URL="https://en.wikipedia.org/wiki/Logical_shift"]right-shift[/URL]). If, for some reason, you'd like to emulate the circuit instead, almost all programming languages (for example, [URL="https://en.wikipedia.org/wiki/Bitwise_operations_in_C"]C[/URL], [URL="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators"]JavaScript[/URL], or [URL="https://wiki.python.org/moin/BitwiseOperators"]Python[/URL]) provide operators for these gates.
[/FONT]
[FONT=Source Code Pro]For example, here is a simple circuit:[/FONT]
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

[FONT=Source Code Pro]After it is run, these are the signals on the wires:[/FONT]
d: 72
e: 507
f: 492
g: 114
h: 65412
i: 65079
x: 123
y: 456 

[FONT=Source Code Pro]In little Bobby's kit's instructions booklet (provided as your puzzle input), what signal is ultimately provided to wire a?[/FONT]

Mein Problem liegt darin, wie ich aus dem Input die jeweiligen Variablen extrahieren bzw initialisieren soll.

k AND m -> n [COLOR=#000000]as RSHIFT 2 -> at

In meinem Code kopier ich diesen INput ja am besten als String rein. Da kann ich dann immer Substrings (bspw. "x OR ai -> aj") machen und da müsst ich dann ja die Variablen x, ai und aj erstellen ... wie soll das gehn?

Hoffe die Problematik und die Aufgabenstellung sind klar ^^
