تصنيف الفقاعة عبارة عن خوارزمية فرز بسيطة. خوارزمية الفرز هذه هي خوارزمية تستند إلى مقارنة يكون فيها كل زوج من العناصر المجاورة
|
|||
|
|
مقارنة ويتم تبديل العناصر إذا لم تكن في النظام. تقوم هذه الخوارزمية بالفرز في المكان بمعنى أنه لا يقوم بإنشاء مصفوفة جديدة بينما
|
|||
|
|
تنفيذ عملية الفرز.
|

|

#### مثال
|

|
|
|

|

[الرسوم المتحركة من BubbleSort](http://www.sorting-algorithms.com/bubble-sort)
|
|||
|
|
|
|||
|
|
`array = <a href='https://repl.it/CXif' target='_blank' rel='nofollow'>5, 1, 4, 2, 8]
|
|||
|
|
|
|||
|
|
First Pass:
|
|||
|
|
( 5 1 4 2 8 ) –> ( 1 5 4 2 8 ), Here, algorithm compares the first two elements, and swaps since 5 > 1.
|
|||
|
|
( 1 5 4 2 8 ) –> ( 1 4 5 2 8 ), Swap since 5 > 4
|
|||
|
|
( 1 4 5 2 8 ) –> ( 1 4 2 5 8 ), Swap since 5 > 2
|
|||
|
|
( 1 4 2 5 8 ) –> ( 1 4 2 5 8 ), Now, since these elements are already in order (8 > 5), algorithm does not swap them.
|
|||
|
|
|
|||
|
|
Second Pass:
|
|||
|
|
( 1 4 2 5 8 ) –> ( 1 4 2 5 8 )
|
|||
|
|
( 1 4 2 5 8 ) –> ( 1 2 4 5 8 ), Swap since 4 > 2
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )
|
|||
|
|
Now, the array is already sorted, but our algorithm does not know if it is completed. The algorithm needs one whole pass without any
|
|||
|
|
swap to know it is sorted.
|
|||
|
|
|
|||
|
|
Third Pass:
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )
|
|||
|
|
( 1 2 4 5 8 ) –> ( 1 2 4 5 8 )

#### [تعقيد الخوارزمية](https://www.freecodecamp.com/videos/big-o-notation-what-it-is-and-why-you-should-care)
|
|||
|
|
|
|||
|
|
**أسوأ ومتوسط زمن التعقيد:** O (n \* n). حالة أسوأ تحدث عندما يتم فرز صفيف عكس أي أن العناصر في ترتيب تنازلي
|
|||
|
|
|
|||
|
|
**أفضل تعقيد لحالة الوقت:** O (n). تحدث حالة أفضل عندما يتم فرز الصفيف بالفعل.
