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? A. Yes B. No​
