1.	What is the average number of comparisons used in a heap sort algorithm?(a) N log N-O(N)(b) O(N log N)-O(N)(c) O(N log N)-1(d) 2N log N + O(N)The question was posed to me during an interview.This is a very interesting question from Heapsort in section Sorting of Data Structures & Algorithms II
Answer» Correct answer is (d) 2N LOG N + O(N) The best I can explain: The AVERAGE number of COMPARISONS in a heapsort algorithm is mathematically found to be 2N log N + O(N).
