1.	The post-order traversal of a binary tree is O P Q R S T. Then possible pre-order traversal will be ________(a) T Q R S O P(b) T O Q R P S(c) T Q O P S R(d) T Q O S P RThis interesting question is from Binary Trees topic in division Binary Trees of Data Structures & Algorithms II have been asked this question by my school principal while I was bunking the class.
Answer» Correct answer is (C) T Q O P S R For explanation: The last, second last nodes visited in post-order TRAVERSAL are root and it’s right CHILD respectively. Option T Q R S O P can’t be a pre-order traversal, because nodes O, P are visited after the nodes Q, R, S. Option T O Q R P S, can’t be valid, because the pre-order sequence GIVEN in option T O Q R P Sand given post-order traversal creates a tree with node T as root and node O as left subtree. Option T Q O P S R is valid. Option T Q O S P R is not valid as node P is visited after VISITING node S.
