Question

During the operation of BUILD HEAP on the array [11,7,5,6,19,13,2,4,3] it will call MAX HEAPIFY several times. What is the order of swap operations on the heap? The array index for Root begins at 1 which points to element value "11".

Answer 1

During the BUILD HEAP operation on the given array, there are three swap operations that occur.

Step-by-step explanation:

During the operation of BUILD HEAP on the array [11,7,5,6,19,13,2,4,3], the swaps that occur to create the heap are as follows:

1. Swap 11 with 4: [11, 7, 5, 6, 19, 13, 2, 4, 3]

2. Swap 11 with 13: [13, 7, 5, 6, 19, 11, 2, 4, 3]

3. Swap 19 with 3: [13, 7, 5, 6, 19, 11, 2, 4, 3]

These swaps ensure that the maximum element is at the root of the heap and that the heap property is maintained.
