Given two non-empty binary trees s and t, check whether tree t has exactly the same structure and node values with a subtree of s. A subtree of s is a tree consists of a node in s and all of this node's descendants. The tree scould also be considered as a subtree of itself. E...
Given two non-empty binary treessandt, check whether treethas exactly the same structure and node values with a subtree ofs. A subtree ofsis a tree consists of a node insand all of this node’s descendants. The treescould also be considered as a subtree of itself. Example 1: Given tre...
Leetcode 543. Diameter of Binary Tree 题目描述:找出二叉树的最长直径(也就是所以节点连成最长的路径长度) 题目链接:Leetcode 543. Diameter of Binary Tree 题目思路:用到的就是经典的递归返回值的形式,不断返回左子树和右子树的深度,然后过程中更新最长的路径。 代码如下 参考链接 543. Diameter of Binary Tr...
Given tree s: 3 / \ 4 5 / \ 1 2 Given tree t: 4 / \ 1 2 Return true, because t has the same structure and node values with a subtree of s. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. Example 2: ...
