FW: Graph traversal when nodes are indirectly connected with references

[Sravani Kambhampati]

I have a graph with disjoint sets of nodes connected indirectly with a 
reference as shown below. Given an id is it possible to get the leaf node when 
the depth is unknown?

[
    { id: A, child: { ref: B } },
    { id: B, child: { ref: C } },
    { id: C, child: { ref: D } },
    .
    .
    { id: Y, child: { ref: Z } }
]
