1.	What may be the psuedo code for finding the size of a tree?(a) find_size(root_node–>left_node) + 1 + find_size(root_node–>right_node)(b) find_size(root_node–>left_node) + find_size(root_node–>right_node)(c) find_size(root_node–>right_node) – 1(d) find_size(root_node–>left_node + 1The above asked question is from Binary Trees using Linked Lists in chapter Binary Trees of Data Structures & Algorithms IThis question was posed to me in a job interview.
Answer» CORRECT choice is (a) find_size(root_node–>left_node) + 1 + find_size(root_node–>right_node) Easy explanation - Draw a tree and analyze the expression. we are always taking size of left subtree and right subtree and adding root VALUE(1) to it and FINALLY PRINTING size.
