A possible representation is two indexed lists, one of names, the other of phone numbers:
Name Telephone Number
Implicitly, telephone number Ti belongs to the person with the name Ni. There is no order imposed on the list of names.
We do not need, for example, the page and column structure of the telephone book. A linear structure is what we need to solve the problem.
