Given a BST, which traversal method would allow you to turn it into a min heap using N
heap insertions calls in O(N) worst case runtime?
Implement the process described above in as-close-to-Java code/no English, write the
method "changeBSTintoMinHeap" which takes in a BSTNode (i.e. root) and returns a
minHeap. You may use helper methods. You can use code from slides to help you. You
must cite all the sources you used. You cannot simply copy and paste code from other
resources (besides slides). Your work must be your own.
Assume we have k heaps, each with a maximum of n items. These are to be combined into a single heap. Each of the following sub-parts provides a different method for merging the heaps, and you are required to calculate the large O running time for each method.
We build a new linked list, L, that is empty. We continually remove the highest priority element from each of the k piles hi and insert it at the beginning of L, until hi is empty. The items of L are then transferred to an array and the array is heapified. What is the worst-case running time for a huge O?
For the operation below, provide the worst case running time in terms of n (Big O notation). Briefly justify your answer
