Alan 2 1 3 2

Li 3 5 1 3
'@ | Out-File $fileName -Encoding default

$hash = Get-Content $fileName | Where-Object {$_} | ForEach-Object {
    $array = $_ -split "\s+"
    @{
        $array[0] = [Linq.Enumerable]::Average([int[]]($array[1..($array.Count-1)]))  
    }
} 

if ($hash.Keys -contains $name){
    return "$name->$($hash.$name)"
}
else {
    return "$name=>no $name"
}
