Given the roots of two binary trees root and subRoot, return true if there is a subtree of root with the same structure and node values of subRoot and false otherwise. A subtree of a binary tree tree is a tree that consists of a node in tree and all of this node's descendants. Th...
BinaryTreeNode* pRoot2) { //技巧2:递归结束条件:大树为空,说明已经遍历完了,说明存在;子树为空,就返回假 //1.如果B子树为空,返回真,说明已经遍历完子树了 if (!pRoot2) return true; //2.如果A子树为空,返回假,说明不匹配 if (!pRoot1) return false; //3.如果两个节点不相同...
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...
