/***
Suppose we have some input data describing a graph of relationships between parents and children over multiple generations. The data is formatted as a list of (parent, child) pairs, where each individual is assigned a unique integer identifier.
For example, in this diagram, 3 is a child of 1 and 2, and 5 is a child of 4:
1 2 4
\ / / \
3 5 8
\ / \ \
6 7 9
