Show hintHide hint
Think of it as the nearest smaller number in an arranged list.
Question 2.
What is a successor in a search tree?
Show hintHide hint
Consider it as the nearest larger number in a sorted list.
3Question 3.
What is the function of a predecessor in a search tree?
- It is the largest value
- It is the smallest value
- It is the closest smaller value
- It is the closest larger value
Show hintHide hint
Look for what 'pre-' could signify.
4Question 4.
True or False: A min heap can effectively manage minimum separation constraints.
- True
- False
Show hintHide hint
Think about how elements are retrieved in the heap.
Question 5.
Create an algorithm using a binary search tree structure to manage a list of flight requests defined by their arrival times, ensuring that any new request complies with a minimum separation rule of 3 minutes.
Show hintHide hint
Think about tree properties and how they facilitate minimum separation checks.
Question 6.
Evaluate the performance difference in time complexities between a direct heap implementation and a balanced binary search tree when managing a large number of flight requests.
