Tracing Genealogies

A file has genealogy data for a collection of N people. The first line of the file contains the integer N followed by N additional lines of data. Each of these additional lines specifies a list of children for a single person. The line starts with the name of the person, followed by the number of that person$$s children, followed by the names of the children. Here is an example of a file specifying genealogy information for $10$ people:

$10$

Al $3$ Beth Carol Dino

Beth $1$ Pablo

Carol $3$ Ben Alex Mary

Dino $0$

Pablo $2$ Angela Miguel

Ben $0$

Alex $0$

Mary $0$

Angela $0$

Miguel $0$

For example, Al has three children named Beth, Carol, and Dino; Beth has one child named Pablo; and Dino has no children. You may assume that all names are unique.

Write a program which reads a file of genealogy information and then allows the user to enter pairs of names X and Y$.$ The program then determines whether Y is a descendant of X$,$ and if so$,$ prints a list of names beginning with X and ending with Y$,$ such that each person in the chain is a child of person preceding them on the list. Otherwise, the program states that Y is not a descendant of X$.$
