Question

The number of nodes in a complete binary tree of level 5 is

Answer 1

in a complete binary tree of n nodes is (n+1), where only 1 node exists in bottom-most level to the far left.

Answer 2

Answer:

63

Explanation:

We have to use the formula $(2^n^+^1-1)$ to caluculate the number of nodes in a complete binary tree. where, n is the number of levels. So, here goes the answer,

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