A sorting algorithm where the order of elements having the same key is not changed in the final sequence Is bubble sort stable? Is merge sort stable?
Bucket sort
Assumption: the keys are in the range [0,
N)
Basic idea:
- Create N linked lists ( buckets ) to divide interval [0,N) into subintervals of size 1
- Add each input element to appropriate bucket
- Concatenate the buckets
Expected total time is O(n + N), with n =
size of original sequence
- if N is O(n) sorting algorithm in O(n)!
Now, pull the elements from the buckets into the array At last, the sorted array (sorted in a stable way):
