Nonvisual Arrays. This tutorial will display how to create and use nonvisual arrays in Alice. Nonvisual arrays are collections of any object or data type that don’t necessarily have to be in order in the world as opposed to visual arrays, but they are still ordered in the array structure. We sill use this to store the values of our recursive function so that we don’t have to calculate it each time we want to ask the user to solve for a specific value.. 1. Last Time. What do we want?.
