Convert the following into parentheses expressions into General (N-ary) Tree, Binary Tree andIndention Expressions, then answer the questions.(A (B (C,D), E(F(G,H), I(J) ), K (L(M), N(O,P) ), Q(R,S(T), U(V(W), X,Y,Z) ) ) )Questions:a. Degree of the tree.b. Level of node P.c. Sibling/s of node K.d. Descendant/s of node Q.e. Ancestor/s of node W.
Given a binary tree T and a source node s in it, provide the pseudocode for an iterative algorithm to traverse T starting from s using breadth-first traversal, also known as level-order traversal. Each node in T contains an integer key that can be accessed. Each time a node is visited, its key should be printed. Note: You do not have to implement your algorithm.
Your colleague proposed a different definition of a binary search tree: it is such binary tree with keys in the nodes that for each node the key of its left child (if exists) is bigger than its key, and the key of its right child (if exists) is less than its key. Is this a good definition for a binary search tree?

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_forwardMatch the term with each definition: In a binary tree, the left child (if any) of a node plus its descendants The number of nodes on the longest path from the root to a leaf A node on a path from a node to a leaf Set of nodes, T, such that either T is empty or T is partitioned into three disjoint sets (a single node r, called the root, and two (possibly empty) sets that are binary trees, called left and right subtrees of T).
