[抄题]: Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can be divided into two stages: Search for a node to remove. If…
思路:如果从首部开始依次查找,那么时间是O(n). 既然我们知道要删除的结点i,那么我们就知道它指向的下一个结点j,那么我们可以将j的内容复制到i,然后将i的指针指向j的下一个结点,这样虽然看起来我们删除的是j结点,但是实际删除的是i. 此外还要考虑的问题是:如果结点不存在怎么办?如果结点是尾结点怎么办?链表只有一个结点? public class deleteInode { public static void main(String[] args) { ListNode head = new…

10-5. 在存储模型中使用自定义函数 问题 想在模型中使用自定义函数,而不是存储过程. 解决方案 假设我们数据库里有成员(members)和他们已经发送的信息(messages) 关系数据表,如Figure 10-4 所示: Figure 10-4. A simple database of members and their messages 可能有这种情况,我们不允许入门级的程序员在数据库中创建存储过程,然而,又想封装members和他们发送的messages条数最多的业务逻辑,这个时候我…
