Powershell script to find empty folders in a Directory

Below script finds all empty folders, but also list the folder which has empty folders inside.

$a = Get-ChildItem C:\Scripts -recurse | Where-Object {$_.PSIsContainer -eq $True}
$a | Where-Object {$_.GetFiles().Count -eq 0} | Select-Object FullName

Could someone please suggest me a script to find empty folder which actually does not contain anything (not even a folder or file).

Thanks in advance
