Data Structures | Heap | Question 7

We have a binary heap on n elements and wish to insert n more elements (not necessarily one after another) into this heap. The total time required for this is (A) theta(logn) (B) theta(n) (C) theta(nlogn) (D) theta(n^2)

(A)

A

(B)

B

(C)

C

(D)

D

Answer: (B)
Explanation:

We can reduce the problem to build heap for 2n elements. Time taken for build heap is O(n).

Hence (B) is the correct answer.
