Show hintHide hint
Think about the relationships between parents and children in the structure.
Question 2.
What is the time complexity for building a heap?
Show hintHide hint
Remember the steps involved in creating the heap from an array.
3Question 3.
What is the primary use of heaps?
- To sort data
- To store elements in a linear fashion
- To implement priority queues
- To represent graphs
Show hintHide hint
Consider how you would prioritize tasks in real-life applications.
4Question 4.
True or False: Heap sort has a time complexity of O(n^2).
- True
- False
Show hintHide hint
Recall how sorting with heaps operates compared to other methods.
Question 5.
Given the array [10, 15, 30, 5, 20, 25], build a max heap and explain each step in the process.
Show hintHide hint
Focus on where swaps may occur.
Question 6.
Devise a scenario where heaps can significantly improve performance compared to sorting methods like bubble sort.
Show hintHide hint
Think about how often data changes and how fast you need that information.
