Algorithmus stellt ein Verfahren zur Lösung eines Problems mit einer
+endlichen Anzahl von Schritten dar. In der Prpgrammierung ist ein Algorithmus
+eine Reihe von Anweisungen, die festlegen, was und wie etwas getan werden muss.
+Zielsetzung ist dabei, aus einer gegebenen Eingabe eine entsprechende Ausgabe zu
+erhalten. Beispiele aus der realen Welt für Algorithmen sind Aufbauanleitungen,
+Rezepte, Spielanleitungen und Beipackzettel.</p>

+<p>Das nachfolgende Rezept beschreibt die Zubereitung von Pankcakes:</p>
+<ol>
+<li>3 Eiweiss zu festem Eischnee verarbeiten</li>
+<li>3 Eigelb und 50g Zucker schaumig rühren</li>
+<li>300g Mehl, 300g Milch, 1 TL Backpulver und etwas Salz unter die
+Eigelb-Zuckermasse rühren</li>
+<li>Sollte der Teig zu fest sein, zusätzlich Milch unterrühren</li>
+<li>Den Eischnee unter den Teig heben</li>
+<li>Eine Pfanne mit etwas Fett erhitzen</li>
+<li>Die Pancakes goldgelb ausbacken</li>
+<li>Die Pancakes mit Puderzucker und Ahornsirup servieren</li>

+<p>Damit ein Verfahren als Algorithmus angesehen werden kann, muss es verschiedene
+Eigenschaften erfüllen:</p>
+<ul>
+<li>Determiniertheit: Ein Verfahren ist deterministisch, wenn es bei beliebig
+häufiger Wiederholung für gleiche Eingabewerte und gleichen Rahmenbedingungen
+immer zum gleichen Ergebnis führt.</li>
+<li>Eindeutigkeit (Determinismus): Ein Verfahren ist determiniert, wenn die
+Schrittfolge immer gleich ist und immer zu einem eindeutigen Ergebnis führt.</li>
+<li>Endlichkeit (Terminiertheit): Ein Verfahren ist terministisch, wenn die Anzahl
+der Schritte endlich ist, also wenn das Verfahren nach endlichen Schritten ein
+Ergebnis liefert.</li>
+<li>Korrektheit: Ein Verfahren ist korrekt, wenn es immer zu einem richtigen
+Ergebnis führt.</li>

+<p>Da der Zeitaufwand von Algorithmen aufgrund unterschiedlicher Faktoren
+(Hardware, parallele Verarbeitung, Eingabereihenfolge,…) nicht genau ermittelt
+werden kann, wird diese mit Hilfe der Landau-Notation dargestellt. Diese teilt
+Algorithmen in unterschiedliche Komplexitätsklassen (logarithmisch, linear,
+polynomial,…) ein. Die Komplexität einer Klasse ergibt sich dabei aus der Anzahl
+der Schritte, die abhängig von der Größe der Eingangsvariablen ausgeführt werden
+müssen.</p>

+eine sogenannte Hashfunktion (auch Streuwertfunktion). Wichtig dabei ist, dass
+der Hashcode nur vom Zustand des Schlüssels abhängen darf.</p>

+auch als (Daten-)Sammlungen bezeichnet. Alle Collections-Schnittstellen und
+Klassen befinden sich im Paket <code>java.util</code>. Die Grundformen der Datensammlungen
+sind die Schnittstellen <code>List&lt;E&gt;</code>, <code>Set&lt;E&gt;</code> und <code>Queue&lt;E&gt;</code>. Zu allen
+Schnittstellen existieren konkrete Implementierungen sowie abstrakte Klassen,
+die zum Erstellen eigener Collections-Klassen verwendet werden können.</p>

+<code>PriorityQueue&lt;E&gt;</code> und <code>LinkedList&lt;E&gt;</code> dar. Die Klasse <code>PriorityQueue&lt;E&gt;</code>
+implementiert die Warteschlange als eine Vorrang-Warteschlange. Bei einer
+Vorrang-Warteschlange werden die Elemente gemäß ihrer Wichtigkeit sortiert, das
+heißt, sie funktioniert nicht nach dem FIFO-Prinzip.</p></div></div></div>

+<p>Ein Iterator erlaubt den sequentiellen Zugriff auf die Elemente einer
+Datensammlung. Iteratoren werden durch die Schnittstelle <code>Iterator&lt;E&gt;</code>
+definiert; diese bietet die Methoden <code>boolean hasNext()</code>, <code>E next()</code> und
+<code>void remove()</code>. Die von <code>Iterator&lt;E&gt;</code> abgeleitete Schnittstelle
+<code>ListIterator&lt;E&gt;</code> bietet zusätzliche Methoden zum Verändern einer Liste.</p>

+als <em>Elternknoten</em> und Kinder ohne weitere untergeordnete Knoten als

+mehrere sinnvolle Reihenfolgen:</p>
+<ul>
+<li>Beim Tiefendurchlauf wird ausgehend vom Wurzelknoten zunächst der linke
+Teilbaum mit Tiefendurchlauf besucht, anschließend der rechte Teilbaum</li>
+<li>Beim Breitendurchlauf werden die Knoten nach der Breite des Baumes geordnet
