Q. 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 ?
