amistre64 · Answer

is there more code surrounding it?  can you post a picture of it?

zzr0ck3r · Answer

It is code for a sorting algorithm on the vertices of a graph.

The find function and union functions connect everything in some component to a single vertex, and the book has the following code, but I am starting to thing it is pseudo code.

In terms of what it is doing, it is "attaching vertices" but I am asking if this is some pointer built into the language.
