Bucket sort

Bucket sort, or bin sort, is a sorting algorithm that works by partitioning an array into a number of buckets. Each bucket is then sorted individually, either using a different sorting algorithm, or by recursively applying the bucket sorting algorithm. It is a distribution sort, and is a cousin of radix sort in the most to least significant digit flavour. Bucket sort is a generalization of pigeonhole sort. Bucket sort can be implemented with comparisons and therefore can also be considered a comparison sort algorithm. The computational complexity estimates involve the number of buckets.

Bucket sort works as follows:

  • Set up an array of initially empty “buckets”.
  • Scatter: Go over the original array, putting each object in its bucket.
  • Sort each non-empty bucket.
  • Gather: Visit the buckets in order and put all elements back into the original array.
