What Is Bucket Sort
Bucket sort is a sorting algorithm that works by distributing elements into several 'buckets' based on a specific range or property, then sorting each bucket individually and finally combining them to get the sorted output.

How Bucket Sort Works
The algorithm first creates empty buckets and then places each input element into its respective bucket. Each bucket is then sorted using another sorting technique such as insertion sort or quick sort, and all buckets are concatenated in order to form the final sorted array.

Time Complexity of Bucket Sort
In the best-case scenario, when the input is uniformly distributed and the bucket sizes are balanced, bucket sort can achieve linear time complexity O(n). However, in the worst case where all elements fall into a single bucket, the time complexity may degrade depending on the internal sorting algorithm used.

Space Requirements of Bucket Sort
Bucket sort is not an in-place sorting algorithm. It requires additional space for the buckets and the internal sorting processes, making it more memory-intensive compared to some other sorting algorithms.

Use Cases for Bucket Sort
Bucket sort is especially effective for data that is uniformly distributed over a range, such as decimal numbers between 0 and 1. It is used in applications where performance is critical and the data characteristics are well understood.

Advantages and Drawbacks
The primary advantage of bucket sort is its efficiency on suitable data distributions. However, it requires extra space and careful bucket management to avoid inefficiency. Choosing the right number of buckets and sorting method for each bucket is key to optimal performance.
