UGC-NET | UGC NET CS 2016 Aug – III | Question 34

A priority queue is implemented as a max-heap. Initially, it has five elements. The level-order traversal of the heap is as follows:
20, 18, 15, 13, 12
Two new elements ‘10’ and ‘17’ are inserted in the heap in that order. The level-order traversal of the heap after the insertion of the element is:
(A) 20, 18, 17, 15, 13, 12, 10
(B) 20, 18, 17, 12, 13, 10, 15
(C) 20, 18, 17, 10, 12, 13, 15
(D) 20, 18, 17, 13, 12, 10, 15


Answer: (D)

Explanation: Initially we have:

When we insert 10 and 17:

We have to maintain max-heap, so:

The level-order traversal of the heap after the insertion of the element is 20, 18, 17, 13, 12, 10, 15
So, option (D) is correct.
