What is the time complexity for decreasing priority of key in a maximum ternary heap of n elements?
 
(a) O (log n/ log 3)
 
(b) O (3log n/ log 3)
 
(c) O (n)
 
(d) O (1)
 
This key question is from Ternary heap in section Heap of Data Structures & Algorithms I
 
This question was posed to me in examination.

Correct choice is (b) O (3log n/ log 3)
 
The explanation is: In order to decrease the priority of key in a maximum ternary heap data structure having n elements, it performs downward swapping. So the time complexity for worst case is found to be O (3log n/ log 3).
