.SYNOPSIS
Measures the speed of BucketSort
.DESCRIPTION
This PowerShell script measures the speed of the BucketSort algorithm.
BucketSort is a sorting algorithm that works by distributing the elements
of 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, a generalization of pigeonhole sort
that allows multiple keys per bucket, and is a cousin of radix sort in the
most-to-least significant digit flavor. Bucket sort can be implemented with comparisons
and therefore can also be considered a comparison sort algorithm. The computational
complexity depends on the algorithm used to sort each bucket, the number of buckets
to use, and whether the input is uniformly distributed.

.SYNOPSIS
Measures the speed of CountingSort
.DESCRIPTION
This PowerShell script measures the speed of the CountingSort algorithm.
CountingSort is an algorithm for sorting a collection of objects according to keys
that are small positive integers; that is, it is an integer sorting algorithm. It
operates by counting the number of objects that possess distinct key values, and
applying prefix sum on those counts to determine the positions of each key value in
the output sequence. Its running time is linear in the number of items and the difference
between the maximum key value and the minimum key value, so it is only suitable for direct
use in situations where the variation in keys is not significantly greater than the number
of items. It is often used as a subroutine in radix sort, another sorting algorithm, which
can handle larger keys more efficiently.

.SYNOPSIS
Measures the speed of HeapSort
.DESCRIPTION
This PowerShell script measures the speed of the HeapSort algorithm.
HeapSort is a comparison-based sorting algorithm. Heapsort can be thought of as an
improved selection sort: like selection sort, heapsort divides its input into a sorted
and an unsorted region, and it iteratively shrinks the unsorted region by extracting
the largest element from it and inserting it into the sorted region. Unlike selection
sort, heapsort does not waste time with a linear-time scan of the unsorted region;
rather, heap sort maintains the unsorted region in a heap data structure to more quickly
find the largest element in each step.

MergeSort is an efficient, general-purpose, and comparison-based sorting algorithm.
Most implementations produce a stable sort, which means that the order of equal elements
is the same in the input and output. Merge sort is a divide-and-conquer algorithm that
was invented by John von Neumann in 1945. A detailed description and analysis of bottom-up
merge sort appeared in a report by Goldstine and von Neumann as early as 1948.
