Consider a Binary Heap of size N. We need to find height of it.
Input : N = 6 Output : 2 () / \ () () / \ / () () () Input : N = 9 Output : () / \ () () / \ / \ () () () () / \ () ()
Let the size of heap be N and height be h
If we take few examples, we can notice that the value of h in a complete binary tree is ceil(log2(N+1)) – 1.
N h --------- 1 0 2 1 3 1 4 2 5 2 ..... .....
