Some of the algorithms to check.
Note:
1. Check these on computer rather than using mobile phone.
2. Check out this http://www.algomation.com/help to see how you can see the algorithm step by step in action.
Here is a comparision between different tree traversals
Check these graph related algoriths, which can be executed.
You could create different trees/graphs and see how the algorithm performs on your graphs.
How a binary search tree is created and how nodes are removed from the tree
