Given a node from a Circular Linked List which is sorted in ascending order, write a function to insert a valueinsertValinto the list such that it remains a sorted circular list. The given node can be a reference toanysingle node in the list, and may not be necessarily the smallest valu...
We want to transform this BST into a circular doubly linked list. Each node in a doubly linked list has a predecessor and successor. For a circular doubly linked list, the predecessor of the first element is the last element, and the successor of the last element is the first element. Th...
Convert a BST to a sorted circular doubly-linked list in-place. Think of the left and right pointers as synonymous to the previous and next pointers in a doubly-linked list.Let's take the following BST as an example, it may help you understand the problem better:将一个二叉搜索树就地转化...
circularQueue.Rear(); // 返回 3 circularQueue.isFull(); // 返回 true circularQueue.deQueue(); // 返回 true circularQueue.enQueue(4); // 返回 true circularQueue.Rear(); // 返回 4 分析 这道题可以使用双向链表来设计数据结构,我们只需要在左右两端维护两个dummy节点,就能够保证enQueue元素和获取...

142. 环形链表 II - 给定一个链表的头节点 head ,返回链表开始入环的第一个节点。 如果链表无环,则返回 null。 如果链表中有某个节点,可以通过连续跟踪 next 指针再次到达,则链表中存在环。 为了表示给定链表中的环,评测系统内部使用整数 pos 来表示链表尾连接到链表
