# Bucket Sort

## What is Bucket Sort?

Bucket sort is a sorting algorithm that divides an array into a number of buckets, each containing a subset of the input elements. The elements in each bucket are then sorted using another sorting algorithm or recursively applying the bucket sort algorithm. Finally, the sorted buckets are concatenated to form the sorted array.

### How does Bucket Sort work?

The bucket sort algorithm works as follows:

1. Set up an array of initially empty "buckets".
2. Scatter the input elements into the buckets.
3. Sort each bucket individually using another sorting algorithm or recursively applying the bucket sort algorithm.
4. Gather the sorted buckets into the output array.

The efficiency of bucket sort depends on the distribution of the input elements. If the elements are uniformly distributed across the range of possible values, then bucket sort can achieve linear time complexity. However, if the elements are heavily skewed towards one end of the range, then bucket sort may perform poorly.

### What are the advantages of Bucket Sort?

• It is easy to implement.
• It is efficient for uniformly distributed input elements.
• It can be parallelized, since each bucket can be sorted independently.

### What are the disadvantages of Bucket Sort?

Bucket sort also has some disadvantages:

• It requires extra memory to store the buckets.
• It may perform poorly for heavily skewed input elements.
• It may not be suitable for sorting large datasets.

### Conclusion

Bucket sort is a simple and efficient sorting algorithm that can be used for a wide range of input elements. It is particularly useful for uniformly distributed input elements and can be parallelized for improved performance. However, it may not be suitable for sorting large datasets or heavily skewed input elements.
