Questions / Exercise for You¶

Please try the following exercises to faciliate your learning:

Try testing the app by clicking the Next button in the mobile app, and check if the corresponding Next page is shown. As a cross-check you can refer to this course web site. The Next button in the mobile app and the course web site should be the same.
Open the blocks view for the mobile app, can you locate the logic for deciding which page is the next page?
Based on what you have observed by testing and readind the code, in your own words, can you describe the algorithm of deciding which page is the next page?
Visit the Tree Traversal Wikipedia Page. Do you think our logic for deciding the next page is better to be described as Breath-first or Depth-first? Is the logic traversing by pre-order, in-order, or post-order?
As a Minimum Viable Product, we have chosen not to implement logic for displaying image as well as support for Prev button. As a programming exercise, can you help implementing them? You may start from this location for the starter code and remix it on your own.
