apcsaArraysCountConsecutiveEquals


Given an array of String values, find and return the number of pairs of equal consecutive elements.


HINTS: This is a "compare neighbors" algorithm, so you need to compare the element at index i with the element at index i+1 (or i-1, your choice).  Be careful of off-by-one errors, which are a common issue with this type of algorithm.  Also: how should you compare String values?

apcsaArraysCountConsecutiveEquals(["hi", "hi", "ho", "ho", "ho", "ho", "hi"]) → 4
apcsaArraysCountConsecutiveEquals(["a", "b", "c"]) → 0
apcsaArraysCountConsecutiveEquals([]) → 0

...Save, Compile, Run (ctrl-enter)

public int apcsaArraysCountConsecutiveEquals(String[] arr) { }
