Bucket Sort

Bucket Sort distributes elements into a collection of buckets based on their values, sorts each bucket individually, and concatenates the buckets. It is effective when input values are distributed relatively uniformly over a known range, particularly for floating-point values in a bounded interval.

1
Performance depends heavily on distribution.
2
Average behavior can approach O(n+k) with appropriate assumptions.
3
Worst-case behavior can degrade toward O(n²) depending on the bucket sorting strategy.
4
Useful for uniformly distributed bounded values.
5
Bucket allocation requires additional memory.
