【Leetcode】C语言 101. Symmetric Tree

与之前相同只不过是判断左右节点对应是否相等。

bool MyisSymmetric(struct TreeNode* Left,struct TreeNode* Right) 
{
    if(!Left&&!Right)
        return true;
    if(!Left||!Right)
        return false;
    if(Right->val!=Left->val)
        return false;
    return MyisSymmetric(Left->left,Right->right)&&MyisSymmetric(Left->right,Right->left);
}
bool isSymmetric(struct TreeNode* root) {
    if(root==NULL)
        return true;
    return MyisSymmetric(root->left,root->right);
}
