Answer 1

Imports System

Public Class Program
	Public Shared Sub break_string_in_bracket(ByVal str As String, ByVal index As Integer, ByVal form As String)
        If index = str.Length Then
            Console.WriteLine(form)
        End If

        For i As Integer = index To str.Length - 1
            Dim temp As String = form
            temp += "("
            temp += str.Substring(index, (i + 1) - index)
            temp += ")"
            break_string_in_bracket(str, i + 1, temp)
        Next
