Run Finder

1. The RunFinder class has a constructor that takes an int Array of values and stores them. It also has two accessor methods:

   1. A toString() method which returns a String version of the array in the format:

      int[value0,value1,value2,...,lastValue]

   2. An identifyRuns() method which analyzes the values in the array and returns a string with sequential runs of any value surrounded by parentheses.

   Sample interaction:

    int[] values = {5,1,3,3,6,4,2,6,5,5,5,5,4,2,2,4,3,2,1,3};
    RunFinder rf = new RunFinder(values);
    System.out.println(rf);

   produces: int[5,1,3,3,6,4,2,6,5,5,5,5,4,2,2,4,3,2,1,3]

    System.out.println(rf.identifyRuns());

   produces: 51(33)6426(5555)4(22)43213

2. The LongRunFinder is similar, but includes a third method, identifyLongestRun(), which identifies the single longest run in the array. For that same data set:

    System.out.println(rf.identifyLongestRun());

   produces: 51336426(5555)42243213

   If there is more than a single longest run, the method can identify either one of the longest runs as being the longest.
