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
