MCQ

The main distinguishable characterstic of a binomial heap from a binary heap is that

it allows union operations very efficiently

it does not allow union operations that could easily be implemented in binary heap

the heap structure is not similar to complete binary tree

the location of child node is not fixed i.e child nodes could be at level (h-2) or (h-3), where h is height of heap and h>4

MCQ

An array consist of n elements. We want to create a heap using the elements. The time complexity of building a heap will be in order of

O(n*n*logn)

O(n*logn)

O(n*n)

O(n *logn *logn)

MCQ

Why is heap implemented using array representations than tree(linked list) representations though both tree representations and heaps have same complexities?

for binary heap

-insert: O(log n)

-delete min: O(log n)

for a tree

-insert: O(log n)

-delete: O(log n)

Then why go with array representation when both are having same values ?

arrays can store trees which are complete and heaps are by it

lists representation takes more memory hence memory efficiency is less and go with arrays

array have better caching

all of the mentioned
