  The size of the array is specified in bytes… could be used as: • array of 1000 char values (ASCII codes) • array of 250 int values • array of 125 double values There is no sense in which the size of the array is "known" by the array itself.

  To initialize a grid, GFESuite extensions provide an empty array (set to zeros) guaranteed to be of the correct dimensions. The empty array is called "self._empty". To initialize a grid to a particular value, say 3.0: grid = self._empty + 3.0 . Note: self._empty is not available in Python in general.

  an unsorted array key/value pairs. To enqueue v with key k, append (k, v) to the array in time O(1). To check whether the priority queue is empty, check whether the underlying array is empty in time O(1). To dequeue-min, scan across the array to find an element with minimum key, then remove it in time O(n).

  The queue can be represented by an array for storing the elements. Apart of the array, we should also remember the front (head) and back (tail) of the queue. We must be sure to declare sufficient space for the array (in the following implementation we can store N − 1 elements). 7.2: Push / pop / size / empty function — O(1). 1 queue = [0] * N
