It is important in distributed computer systems to identify
those events (at identifiable points in time) that are concurrent, or
not related to each other in time. A group of concurrent events may
sometimes attempt to simultaneously use the same resource, and this
could cause problems.
In this problem you will be supplied with lists of sequential events
for an arbitrary number of computations, and the identification of an
arbitrary number of messages sent between these computations. Let n
be the number of events. Your task is to write an O(n3) program to
find out how many pairs of events are concurrent
