1. 中序遍历(In-order Traversal):先访问左子树,然后是根节点,最后访问右子树。这种遍历方式可以按照“左-根-右”的顺序访问所有节点。 2. 前序遍历(Pre-order Traversal):先访问根节点,然后是左子树,最后访问右子树。这种遍历方式可以按照“根-左-右”的顺序访问所有节点。 3. 后序遍历(Post-order Traversal...
That's all for now onhow you can implement theinOrdertraversal of a binary tree in Java using recursion. You can see the code is pretty much similar to thepreOrdertraversal with the only difference in the order we recursive call the method. In this case, we callinOrder(node.left)first ...

It’s easy to implement (using recursion of loop). There are three variations of the Depth-first traversal. In-order tree traversal. Preorder Tree traversal Postorder traversal Let’s see how to implement these binary tree traversals in Java and what is the algorithm for these binary tree tra...
