Let generalized Table L = ((a, b), C, ((D, e), f), H), find the length and depth of generalized table, and what are the header and tail of generalized table l?

Let generalized Table L = ((a, b), C, ((D, e), f), H), find the length and depth of generalized table, and what are the header and tail of generalized table l?


The header of the generalized table is (a, b)
The tail of L generalized table is the part after the header, that is, (C, ((D, e), f), H)
The depth of the generalized table is 3
