 Any such representation of sequences should contain all the information as in the original sequence—most importantly, each individual member must be retrievable.However, the length does not have to match directly; even if we want to handle sequences of different length, we can store length data as a surplus member, or as the other member of an ordered pair by using a pairing function.We expect that there is an effective way for this information retrieval process in form of an appropriate total recursive function.
