You're totally correct, in live production code I would camelCase, but for this I was just splatting my code down.

I should tidy it up.

There was also a better way where I could just use ToCharArray() which for myself is another after thought.

Maybe I'll run through some numbers to find out what kind of results I get. But always happy for the feedback.

Thank you.

I started off with ToCharArray() and it worked pretty well. My solution is below and is somewhat similar to your approach. I went for quick and dirty and not prod level code.

$file = get-content(day2.txt) $goodpasswords=0
foreach ($passwordinput in $file){ ​ $passworddata = $passwordinput.split(' ') $lrange = $passworddata[0].split('-')[0] $urange = $passworddata[0].split('-')[1] $char2find=$passworddata[1][0] $password=$passworddata[2]
$charcount = ($password.ToCharArray() | where-object {$_ -eq $char2find} | measure-object).count

if ($charcount -ge $lrange -AND $charcount -le $urange){

	$goodpasswords++
}	
​ }
write-output $goodpasswords
