Problem Statement

Brian Kernighan, in a lecture at the University of Nottingham, described a problem on which this task is based. You are given a a data file of thousands of lines; each of three whitespace separated fields: a date, a one word name and the magnitude of the event. Example lines from the file would be lines like:

Let's start with the solution:
