In this article, I will explain What is Bucket Sort Algorithm and how does it work.
Bucket Sort is a sorting algorithm that works by distributing the elements of an array into a number of buckets, and then sorting the elements within each bucket. It is useful when the input data is uniformly distributed over a range, and the range is known.
The steps for Bucket Sort are as follows:
- Create an array of empty buckets.
- Go through the input array and put each element into the appropriate bucket based on its value.
- Sort each bucket, either using another sorting algorithm or recursively applying the bucket sort algorithm.
- Concatenate the sorted buckets together to get the final sorted array.
The time complexity of bucket sort is O(n + k), where n is the number of elements to be sorted and k is the number of buckets. The space complexity is also O(n + k), as each bucket requires space to hold its elements.
Bucket sort is often used as a subroutine in other sorting algorithms, such as radix sort. It is a relatively simple algorithm that is easy to implement and can be very efficient when used in the appropriate situation.
