Prove that any binary tree of height h (where the empty tree is height 0, and a tree witha single node is height 1) has between h and 2h − 1 nodes, inclusive. A binary tree is onein which every node has at most three edges (at most one to the ’parent’ and two to the’children.’)
Consider a weight balanced tree such that, the number of nodes in the left sub tree is at least half and at most twice the number of nodes in the right sub tree. The maximum possible height (number of nodes on the path from the root to the farthest leaf) of such a tree on k nodes can be described asa) log2 nb) log4/3 nc) log3 nd) log3/2 n
The total number of nodes on the pathways leading from the root to all null links is the definition of a tree's external path length. Show that in every binary tree with N nodes, the difference between the internal and exterior path lengths is 2N.

- A binary tree is \emph{full} if every non-leaf node has exactly two children. For context, recall that we saw in lecture that a binary tree of height $h$ can have at most $2^{h+1}-1$ nodes and at most $2^h$ leaves, and that it achieves these maxima when it is \emph{complete}, meaning that it is full and all leaves are at the same distance from the root. Find $\nu(h)$, the \emph{minimum} number of leaves that a full binary tree of height $h$ can have, and prove your answer using ordinary induction on $h$. Note that tree of height of 0 is a single (leaf) node. \textit{Hint 1: try a few simple cases ($h = 0, 1, 2, 3, \dots$) and see if you can guess what $\nu(h)$ is.}arrow_forwardConsider a completely populated full binary tree of height 10. 1.

- Given a binary tree, find the length of the longest consecutive sequence path.The path refers to any sequence of nodes from some starting node to any nodein the tree along the parent-child connections.The longest consecutive path need to be from parent to child(cannot be the reverse).For example, 1 \ 3 / \ 2 4 \ 5Longest consecutive sequence path is 3-4-5, so return 3. 2 \ 3 / 2 / 1arrow_forwardGiven a binary tree, find the length of the longest consecutive sequence path.The path refers to any sequence of nodes from some starting node to any nodein the tree along the parent-child connections.The longest consecutive path need to be from parent to child(cannot be the reverse.arrow_forwardConsider the Fibonacci sequence F(0)=0, F(1)=1 and F(i)=F(i-1)+F(i-2) for i > 1. For the sake of this exercise we define the height of a tree as the maximum number of vertices of a root-to-leaf path. In particular, the height of the empty tree is zero, and the height of a tree with a single vertex is one.

We are given a complete binary tree with height h and n nodes. The link between a node and its left child is labeled as 0 and the link between a node and its right child is labeled as 1. A path from the root to each external node at the last level can be labeled by an h-tuple (X1, X2, ..., xh) of 1s and Os that lie on its links.
