Another way to find duplicates in two strings.
I think the LINQ way is a way more expressive compared to the loops although conceptually they do the same thing.
Function LINQ(ByVal arr1 As String(), ByVal arr2 As String) As String()
Dim duplicates = From s0 In arr1, s1 In arr2 _
Where s0 = s1 _
Select s0
Return duplicates.ToArray()
End Function
Function Loops(ByVal arr1 As String(), ByVal arr2 As String()) As String()
Dim l As New List(Of String)
For i As Integer = 0 To UBound(arr1)
For j As Integer = 0 To UBound(arr2)
If arr1(i) = arr2(j) Then l.Add(arr1(i))
Next
Next
Return l.ToArray()
End Function
.

Both solutions seems incorrect. You will have doubles — every string will be returned twice.
