I decided to golf up this kumite - for the sanity of the tester, I trim the function definition to remove leading or trailing spaces.
Write-Verbose (Get-Module pester -listAvailable).Version.ToString() function calculate_multiples { (1..999|?{!($_%3) -or !($_%5)}|measure -s).sum }1 + Write-Verbose (Get-Module pester -listAvailable).Version.ToString()
1 1 function calculate_multiples {2 − 3 − $SUM = 0
4 − 5 − 1..999 | ForEach-Object {6 − if (!( $_ % 3) -OR !($_ % 5)) {7 − $Sum += $_
8 − }
9 − }
10 − 11 − return $Sum
3 + (1..999|?{!($_%3) -or !($_%5)}|measure -s).sum12 12 }
