Write the method getLongestRun that takes as its parameter an array of boolean values representing a series of coin flips. The method returns the starting index in the array of a run of maximum size. A run is defined as the repeated occurrence of the same boolean value in two or more consecutive positions in the array. For example, the following array contains two runs of length 3, one starting at index 1 and one starting at index 4. The method may return either of those starting indexes.
