Specific questions asked
We have big log file with 3 columns, the first column is a rider name, the second column is a city name, the final column is a timestamp (32 bit integer). This log file maintains a history of riders. We define a "triple" to be a tuple of three consecutive cities a rider has been to that are ordered by timestamp. Suppose ts1<ts2<ts3<ts4, then we will have the following triples: for Jamie, we have: (city2, city4, city3) , (city4, city3, city1) for Dana, we have: (city4, city3, city1) Write a program to output all the triples in the file and for each triple, output the count of unique riders that have been to that triple.
