Binary Tree Traversals A traversal is an algorithm for visiting some or all of the nodes of a binary tree one and only one time in some defined order. L---moving left, V---visiting the node, R---moving right , the possible combination of traversal: LVR LRV VLR VRL RVL RLV...

Binary search trees A binary search tree is a binary tree where all elements in the left subtree are less than elements in the right subtree As we saw earlier, inorder traversal is a b c d e f g h i j which is in sorted order So this is a binary search tree 3 Binary search tre...
