NOTE: This problem is deliberately phrased to be convoluted/complex. Sometimes we are given problem statements that could be phrased a lot simpler, and it takes a bit of analysis to see that the problem is not as complex as it looks. This is an exercise in the same. Define a function that when passed an ArrayList of Integer objects, returns true if it is in a "nice" order, and false otherwise. A "nice" order is defined as an order where each item that is not at the two ends, is higher than or equal to one of its neighbour, and lower than or equal to the other.
