preorder: root-left-right inorder: left-root-right postorder: left-right-root order指的是root的位置。 recursive算法比较简单,iterative算法比较难想,可是leetcode原题都说了: recursive method is trivial, could you do iteration? 144.Binary Tree Preorder Traversal /*iterative*/ public List<Integer> p...
Preorder sequence: A B D E C F In a Preorder sequence, leftmost element is the root of the tree. So we know ‘A’ is root for given sequences. By searching ‘A’ in Inorder sequence, we can find out all elements on left side of ‘A’ are in left subtree and elements on righ...
