<# .SYNOPSIS Measures the speed of BubbleSort .DESCRIPTION This PowerShell script measures the speed of the BubbleSort algorithm. BubbleSort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort, is named for the way smaller or larger elements "bubble" to the top of the list. .PARAMETER numIntegers Specifies the number of integers to sort .EXAMPLE PS> ./measure-BubbleSort.ps1 🧭 0.729 sec to sort 1000 integers by BubbleSort .LINK https://github.com/fleschutz/PowerShell .NOTES Author: Markus Fleschutz | License: CC0 #> param([int]$numIntegers = 1000) class BubbleSort { static Sort($targetList) { $n = $targetList.Count for ($i = 0; $i -lt $n; $i+=1) { for ($j = 0; $j -lt $n-1; $j+=1) { if($targetList[$j] -gt $targetList[$j+1]) { $temp = $targetList[$j+1] $targetList[$j+1]=$targetList[$j] $targetList[$j]=$temp } } } } } $list = (1..$NumIntegers | foreach{Get-Random -minimum 1 -maximum $numIntegers}) $stopWatch = [system.diagnostics.stopwatch]::startNew() [BubbleSort]::Sort($list) [float]$elapsed = $stopWatch.Elapsed.TotalSeconds $elapsed3 = "{0:N3}" -f $elapsed # formatted to 3 decimal places "🧭 $elapsed3 sec to sort $numIntegers integers by BubbleSort" exit 0 # success
