| Now you need to fill in a table in order to store the area calculated for each state. The functor [[:set_lookup_table_value|Set Lookup Table Value]] updates a lookup table placing a value to a position defined by a key. To fill in the entire lookup table, you need to develop a loop that enables this functor to browse through the lookup table. To close this loop, you will need a functor that is key to the development of dynamic models. Here we introduce the concept of Mux functor. | Now you need to fill in a table in order to store the area calculated for each state.
