Question

No of nodes in complete binary tree of level 5

Answer 1

2^n-1=2^5-1=32-1=33
...

Answer 2

Answer:

63

Explanation:

We need to use the following formula for calculating the number of nodes in a complete binary tree

$(2^n^-^1-1)$

where n is the number of levels.

so,

$(2^(^5^-^1^)-1) = (2^6-1) = 64-1 = 63$
