Suppose that you had a collection of “widgets;’ stored in a rectangular grid (like a table). You could reference the widget stored in the ith row, jth column by using the ordered pair of numbers, (i, j). Describe how you could create a new set of widget addresses where each address is a single number. For example, instead of referring to the widget in row 12, column 30 using (12, 30), you might say that its address is 1230.
