Populate each next pointer to point to its next right node. If there is no next right node, the next pointer should be set toNULL. Initially, all next pointers are set toNULL. Example: Input: {"$id":"1","left":{"$id":"2","left":{"$id":"3","left":null,"next":null,"rig...
TreeLinkNode *left; TreeLinkNode *right; TreeLinkNode *next; } Populate each next pointer to point to its next right node. If there is no next right node, the next pointer should be set toNULL. Initially, all next pointers are set toNULL. Note: You may only use constant extra space...
Node *left; Node *right; Node *next; } 填充它的每个 next 指针,让这个指针指向其下一个右侧节点。如果找不到下一个右侧节点,则将 next 指针设置为 NULL。 初始状态下,所有 next 指针都被设置为 NULL。 示例: 输入:{“id":"1","left":{"id”:“2”,“left”:{“id":"3","left":null,"next...
