The '''turning editing on''' option can be found as a link in the administration block or as a button at the top right of a course homepage. This option is only available to teachers of the course who also have editing rights or to those users who are assigned site administration rights. Turn editing on allows teachers to change the appearance and functionality of the course. You can turn editing off again by pressing the button or the admin block link again (both now renamed turn editing off!)
 
 
 
You will see these icons frequently when editing is on:
 
 
 
:[[Image:Edit.gif]] - the edit icon lets you alter/update whatever resource or activity it is next to.
 
 
 
:[[Image:Help.gif]] - the help icon will popup a relevant help window
 
 
 
==Blocks==
 
 
 
Existing blocks can be moved up, down or sent to the right or left column of the course. They can also be set to visible or hidden. They can be removed completely by pressing the X icon.
 
 
 
You will see these icons when editing blocks:
 
 
 
:[[Image:Block open.gif]] - the block is visible. Clicking the eye will hide the block from students
 
 
 
:[[Image:Block closed.gif]] - the block is hidden. Clicking the eye will show the block to students
 
 
 
:[[Image:Block delete.gif]] - clicking this icon will remove the block from the course
 
 
 
:[[Image:Block up.gif]] - this icon will move the block upwards
 
 
 
:[[Image:Block down.gif]] - this icon will move the block down
 
 
 
:[[Image:Block left.gif]] - this icon will move the block to the bottom of the left column
 
 
 
:[[Image:Block right.gif]] - this icon will move the block to the bottom of the right icon
 
 
 
==Sections==
 
 
 
Topics or weeks (either casn also be refered to as sections) can be moved up or down to change the order in which the course is dispayed. Sections can also be hidden from, or made visible to, learners. If the course is topic based then a topic can be set as current (or indeed the current status can be removed).
 
 
 
:[[Image:Open.gif]] - the open-eye icon means an item is visible to students. It will close when you click on it
 
 
 
:[[Image:Closed.gif]] - the closed-eye icon means an item is hidden from students. It will open when you click on it.
 
 
 
:[[Image:Marker.gif]] - the marker icon allows you to make a section current
 
 
 
The following icons are visible when editing is both on and off
 
 
 
:[[Image:One.gif]] - This icon is used to show only the selected section
 
 
 
:[[Image:All.gif]] - This icon is used to show all sections in a course
 
 
 
Einführung
 
 
 
Unter Sortieren versteht man allgemein den Prozess des Anordnens einer
 
gegebenen Menge von Objekten in einer bestimmten Ordnung. Die Ordnung
 
hängt dabei von der Art der Objekte ab, z.B. wird man Texte alphabetisch und
 
Zahlen numerisch sortieren.
 
 
 
Aufgabe bei der Sortierung ist es, Datensätze, die über einen oder mehrere
 
Schlüssel (eindeutig) charakterisiert sind, in eine geordnete Folge zu bringen.
 
Dabei muss auf den Schlüsseln der Datensätze eine (partielle) Ordnung definiert
 
sein, und damit auch eine Vergleichsfunktion.
 
 
 
Die Sortierung von Datenmengen erleichtert z.B. das Suchen bestimmter
 
Elemente (über ihren Schlüsselwert) oder auch das Entdecken von Duplikaten.
 
In der Literatur werden verschiedene Sortieralgorithmen beschrieben, die sich
 
jedoch zum Teil in ihrem Ressourcenverbrauch (Speicher, CPU) unterscheiden.
 
Ein „guter“ Sortieralgorithmus sollte effizient mit den Ressourcen umgehen,
 
also möglichst wenig Speicher und CPU-Zeit verbrauchen.
 
Ziel dieses Kurses ist es, die Algorithmen dieser Verfahren zu verstehen und
 
die jeweilige Komplexität zu bestimmen.
 
Hier geht's um das Sortieren durch Einfügen, das Sortieren durch Auswählen sowie das das Sortieren durch Vertauschen (Bubblesort), also um die drei einfachen Sortieralgorithmen. Dazu verwenden wir Arrays.
