We define a runs in a list is a series of 2 or more adjacent elements of the same value. Write a method to return the number of runs in the input list. Test case 1: countRuns([1,2,2,2,3])=1 (which is 2,2,2) Test case 2: countRuns ([1,1,2,3,4,5,5])=2 (which is 1,1 ; and 5,5 ) We define a runs in a list is a series of 2 or more adjacent elements of the same value.
