tree traversals , how to approach?
Let T be a rooted binary tree whose vertices are labelled with symbols a, b, c, d, e, f, g, h, i, j, k. Suppose the inorder and postorder traversals of T produce the following sequences. inorder: a, b, c, d, e, f, g, h, i, j, k postorder: a, c, b, e, f, h, j, k, i, g, d How many leaves does the tree have?

Tree traversals
For a binary tree T, preorder traversal yields: 11,8,6,4,7,10,19,43,31,29,37,49 and inorder traversal yields: 4,6,7,8,10,11,19,29,31,37,43,49 The height of the T is ________________.

Binary Tree construction
Given the preorder/postorder and inorder traversal of a binary tree, we can always construct a unique binary tree (I think so, correct me if I am wrong) Construct a binary tree with the nodes A, B, C such that its preorder traversal is ABC and its inorder traversal is CAB.

Algorithm
1. What is the time complexity to design BST from given postorder and inorder traversal? 2. What is the time complexity to design BST from given postorder only. I know time to design BST from Preorder is O(n).

DFS using Stack
Could someone please explain Depth first Search using Stack? I have found different algorithms for handling the visited flag and the way the nodes are pushed. I am having problems in solving these types of questions  Find the nodes or number of nodes that are pushed onto stack more than once? Could someone please help with a small example?

Kerala PSC AP Exam
A binary search tree contains the numbers 1, 2, 3, 4, 5, 6, 7, 8. The tree is traversed in preorder and the values of in each node printed out the sequence of values obtained is 5,3,1,2,4,6,8,7. If the tree is traversed in post order, the sequence obtained would be A) 8 7 6 5 4 3 2 1 B) 1 2 3 4 8 7 6 5 C) 2 1 4 3 6 7 8 5 D) 2 1 4 3 7 8 6 5
