Binary tree iterator for inorder traversal
WebIn this method, we have to use a new data structure-Threaded Binary Tree, and the strategy is as follows: Step 1: Initialize current as root. Step 2: While current is not NULL, If current does not have left child a. Add current’s value b. Go to the right, i.e., current = current.right Else a. http://duoduokou.com/algorithm/40876164651616882688.html
