A very nervous person wants to select an access code for the alarm on their house. They have very specific instructions, as they don$$t want to make it easy for someone to guess their code.

I. The code must consist of six digits $(0-9).$

II$.$ The code cannot have six digits all the same $($ex: $000000,111111,$ etc.$).$

III. The code cannot have six consecutive numbers ascending or descending $($ex: $012345,123456,987654,543210,$ etc.$).$

IV$.$ The first and last digits cannot be a $0.$

How many different access codes does this very nervous person have to choose from?
