Was confused abit about TREE SYMMETRIC question. He was expecting a recursive solution. But explained him a solution using tree inorder/preorder/postorder traversals. Explained him, and wrote code for different traversals and some functions to integrate all.
Finally he seems convincing with my approach and solution.
