Bucket Sort

Bucket Sort is a non-comparison sorting algorithm that divides the input array into a number of buckets, each capable of holding a range of values. Elements from the input array are distributed into these buckets based on their value ranges, and then each bucket is sorted individually, typically using another sorting algorithm or recursively applying bucket sort. Finally, the sorted buckets are concatenated to produce the sorted array.

Advantages:

  1. Efficient for sorting elements uniformly distributed over a range.
  2. Can be faster than comparison-based sorting algorithms for certain types of input data.
  3. Can be parallelized easily, making it suitable for parallel computing environments.

Disadvantages:

  1. Requires prior knowledge of the data range to determine the bucket size, which may not always be available.
  2. May not perform well if the input data is not uniformly distributed.
  3. Extra space is required for creating buckets, which can be a concern for large datasets.

Quick Sort:

Quick Sort is a comparison-based sorting algorithm that follows the divide-and-conquer strategy. It selects a pivot element from the input array, partitions the array into two subarrays such that all elements less than the pivot are on the left and all elements greater than the pivot are on the right. The process is then recursively applied to the subarrays until the entire array is sorted....
