Given a binary treerootand a linked list withheadas the first node. Return True if all the elements in the linked list starting from theheadcorrespond to somedownward pathconnected in the binary tree otherwise return False. In this context downward path means a path that starts at some node ...
Can you solve this real interview question? Linked List in Binary Tree - Given a binary tree root and a linked list with head as the first node. Return True if all the elements in the linked list starting from the head correspond to some downward path

Given a binary tree, flatten it to a linked list in-place. For example, Given 1 / \ 2 5 / \ \ 3 4 6 The flattened tree should look like: 1 \ 2 \ 3 \ 4 \ 5 \ 6 思路: 递归处理每个结点,如果结点左孩子为空,则无需处理。否则先将结点右孩子挂到左孩子最右边的子孙结点,然后将左...
还是写的时候想的太简单了。这道题目要求是 in place. 相应的解法是, publicclassSolution{publicvoidflatten(TreeNode root){if(root==null)return;flattenTree(root);}publicTreeNodeflattenTree(TreeNode root){if(root==null)returnnull;TreeNode leftTail=flattenTree(root.left);TreeNode rightTail=flattenTree...
Given a binary tree, flatten it to a linked list in-place. For example, Given tree The flattened tree should look like: flattened click to show hints. Hints: If you notice carefully in the flattened tree, each node's right child points to the next node of a pre-order traversal. ...
