Answer 1

Imports System

Public Class Program
    Public Shared Sub printMatrix(ByVal matrix As Integer()())
        Dim rows As Integer = matrix.Length

        For i As Integer = 0 To rows - 1
            Dim cols As Integer = matrix(i).Length

            For j As Integer = 0 To cols - 1
                Console.Write(matrix(i)(j) & " ")
            Next

            Console.WriteLine()
        Next
    End Sub

    Public Shared Sub Main(ByVal args As String())
        Dim jaggedMatrix As Integer()() = New Integer(2)() {}

        jaggedMatrix(0) = New Integer() {1, 2, 3}
        jaggedMatrix(1) = New Integer() {4, 5}
        jaggedMatrix(2) = New Integer() {6, 7, 8, 9}

        printMatrix(jaggedMatrix)
    End Sub
End Class
