Question

Function f(ByVal x As String, ByVal y As Integer, ByVal z As Integer, ByVal w As Integer, ByRef t As String) As String
    If Length(x) < w Then      // Definition for Length below
      Return t
    End If
    If y = z Then
        t = t + SubStr(x, w, 1)    // Definition for SubStr below
        z = 1
    Else
        z = z + 1
    End If
    w = w + 1
    Return f(x, y, z, w, t)

End Function
Function f1(ByVal x As String, ByVal y As Integer) As String
    Return (f(x, y, 1, 1, ""))
End Function

I am not a VB programmer, but I assumed for the most part that the syntax is C like, I received the program above from a non-technical recruiter with the following input f1(“enritcde3 dtyeds4t8”, 2) . From my understanding the following output would be (“enritcde3 dtyeds4t8”,2,2,2,“”)
. Am I missing something???

Just converted it over to Vb.Net and the output is “nice test”.

Its parsing the even position characters in the string excluding the space.
