Given two binary trees, write a function to check if they are equal or not.
Two binary trees are considered equal if they are structurally identical and the nodes have the same value.
思路:对二叉树进行遍历即可。递归求解:
1 class Solution { 2 public: 3 bool isSameTree( TreeNode *p, TreeNode *q ) { 4 if( !p && !q ) { return true; } 5 if( p && q && p->val == q->val ) { 6 return isSameTree( p->left, q->left ) && isSameTree( p->right, q->right ); 7 } 8 return false; 9 } 10 };
