Sub Main()
Dim OpiningBalance = 200.0
Dim StratWithdraws() = {40, 20, 80, 100, 20, 140, 60}
Dim ClosingBalance = StratWithdraws.Aggregate(OpiningBalance, Function(Opening, Withdrawal) _
(If(Withdrawal <= Opening, (Opening - Withdrawal), Opening)))
Console.WriteLine("Closing balance: {0}", ClosingBalance)
Console.ReadLine()
End Sub
End Module
