PowerShell is powerful. You can write concise, well formulated, functional-style code. Recently I got the following quiz:

You’ve got $100. You have to buy exactly 100 animal, at least 1 dog, 1 cat and 1 mouse. 1 dog costs $15, 1 cat costs $1, 1 mouse costs $0.25.

There can be  many ways to solve it. But look at this one line solution. It is quite impressive what you can do with PowerShell [code language=“powershell”] 1..98 | % { $dog = $_ 1..98 | % { $cat = $_ @{ “Dog” = $dog “Cat” = $cat “Mouse” = 100 - $dog -$cat } } } | ? { $_.Mouse -gt 0 } | ? { $_.Dog * 15 + $_.Cat * 1 + $_.Mouse * 0.25 -eq 100 } [/code] This solution uses ranges, dynamic objects (PSObject), nested for loops, implicit returns and advanced filtering. All that is is out-of-the-box PowerShell.
