If the number of levels is L, the maximum number of nodes N in a binary tree is N = 2L-1.
For L = 5, N equates to 31 thus.
For any given level n there will be a maximum of 2n nodes.

if u assign a 0th level to root of binary tree then,the minimum no. of nodes for depth K is k+1.
Incomplete Binary Tree is a type of binary tree where we do not apply the following formula: 1. The Maximum number of nodes in a level is 2
Level N of a binary tree has, at most, 2^N nodes. Note that the root node is regarded as being level 0. If we regard it as being level 1, then level N would have 2^(N-1) nodes at most.
A full tree is a tree where all nodes except the leaves have the maximum number of children. For a BST, that would be two children per node. A complete tree is the same thing, except that the bottom level does not need to be full. It can be missing leaf nodes, however the ones present must be shifted to the left.
If N>1, there are (2N-1) - (2N-1-1), otherwise, 1 nodes in the Nth level of a balanced binary tree.
The height of a complete binary tree is in terms of log(n) where n is the number of nodes in the tree. The height of a complete binary tree is the maximum number of edges from the root to a leaf, and in a complete binary tree, the number of leaf nodes is equal to the number of internal nodes plus 1. Since the number of leaf nodes in a complete binary tree is equal to 2^h where h is the height of the tree, we can use log2 to find the height of a complete binary tree in terms of the number of nodes.
Complete Binary tree: -All leaf nodes are found at the tree depth level -All nodes(non-leaf) have two children Strictly Binary tree: -Nodes can have 0 or 2 children
Complete Binary tree: All leaf nodes are found at the tree depth level and All non-leaf nodes have two children. Extended Binary tree: Nodes can have either 0 or 2 children.
A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.

In general: There are 2n-1 nodes in a full binary tree. By the method of elimination: Full binary trees contain odd number of nodes. So there cannot be full binary trees with 8 or 14 nodes, so rejected. With 13 nodes you can form a complete binary tree but not a full binary tree. So the correct answer is 15. niraj
