示例1: computeExact
/** Computes and returns the neighbourhood function of the specified graph by multiple breadth-first visits.
*
* <p>This method returns an array of longs. When some values of the function are near 2<sup>63</sup>, it
* provides an exact value, as opposed to {@link #compute(ImmutableGraph, int, ProgressLogger)}.
*
* @param g a graph.
* @param threads the requested number of threads (0 for {@link Runtime#availableProcessors()}).
* @param pl a progress logger, or <code>null</code>.
* @return the neighbourhood function of the specified graph as an array of longs.
