Try these first

1. 1.

   What data structure is used to represent hierarchical data?

   Hint

   Think about how directories are organized on your computer.

2. 2.

   What type of heap is used to schedule high-priority tasks?

   Hint

   It manages tasks by their priority level.

3. 3.

   What is the primary function of a trie in computing?

   • To represent graphs
   • To store prefixes
   • To manage priority tasks

   Hint

   Remember trie applications in search engines.

4. 4.

   True or False: A min-heap allows for the quick retrieval of the lowest-priority task.

   • True
   • False

   Hint

   Consider how task prioritization works with heaps.

5. 5.

   Design a simple binary tree for a decision-making AI for a game. Describe how it can be structured.

   Hint

   Structure your decisions hierarchically.

6. 6.

   Given a scenario of a task scheduler, choose between heap and array for managing tasks. Justify your choice.

   Hint

   Consider how access times vary between the two data structures.
