That's all abouthow to implement inOrder traversal of a binary tree in Java using recursion. You can see the code is pretty much similar to the preOrder traversal with the only difference in the order we recursive call the method. In this case, we callinOrder(node.left)first and then ...
Approach 2: Iterating method using Stack 迭代(基于栈) The strategy is very similiar to the first method, the different is using stack. 伪代码如下(摘录自Wikipedia Tree_traversal) iterativeInorder(node) parentStack=empty stackwhile(notparentStack.isEmpty()ornode ≠ null)if(node ≠ null) parent...
Here is our complete Java program to implement iterative inorder traversal in Java. Similar to the iterative PreOrder algorithm we have used the Stack data structure to convert the recursive algorithm to an iterative one, one of the important things every programmer should remember. We have used...
Iterative We can use a stack toemulate the recursion. We first push the left nodes as many as possible, if not, we push the right sub trees. This gives an inorder traversal. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 ...

2.8 In Binary Tree, Inorder successor of a node is the next node in Inorder traversal of the Binary Tree. Inorder Successor is NULL for the last node in Inoorder traversal. In Binary Search Tree, Inorder Successor of an input node can also be defined as the node with the smallest key...
Similar to thepreOrder()method inthe last example, there is anotherinOrder()method that exposes inorder traversal to the public and calls this private method, which actually performs theInOrdertraversal. This is the standard way to write a recursive method that takes input; it makes it easier...
right == null : false; } } // root of binary tree TreeNode root; /** * Java method to print tree nodes in PreOrder traversal */ public void preOrder() { preOrder(root); } /** * traverse the binary tree in PreOrder * @param node - starting node, root */ private void preOr...
order traversal was readable, clear, and concise. You should always prefer such an algorithm over an iterative one, but if you have been asked to solve this problem without recursion then you have no choice. In order to convert that recursive algorithm to aniterativeone, you can use a ...
