# Quicksort
|
||||
- Pivoelement muss zuerst bestimmt werden, idealerweise der Median (Median: nicht ohne Sortierung bestimmbar)
|
||||
- Prinzip: Teile und herrsche
|
||||
## Beipiel:
|
||||
253 401 24 590 281
|
||||
253 24 281 401 590
|
||||
\\\\
|
||||
- Elemente werden mit Pivoelement verglichen und avor oder dahinter einsortiert
|
||||
- Vorgang wird wiederholt, bis nur einelemntigre Teilmengen über sind (Rekursion)
|
||||
## Übung:
|
||||
58 12 3 7 62
|
||||
3 7 12 58 62
