101. Symmetric Tree

Given a binary tree, check whether it is a mirror of itself (ie, symmetric around its center).For example, this binary tree [1,2,2,3,4,4,3] is symmetric: 1 / \ 2 2 / \ / \3 4 4 3

102. Binary Tree Level Order Traversal

Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level).For example:Given binary tree [3,9,20,null,null,15,7], 3 / \ 9 2

C++ STL--stack/queue 的使用方法

http://www.cnblogs.com/mfryf/archive/2012/08/09/2629992.html1、stackstack 模板类的定义在头文件中。stack 模板类需要两个模板参数,一个是元素类型,一个容器类型,但只有元素类型是必要的,在不指定容器类型时,默认的容器类型为deque。定义stack 对象的示例代码如下:stack s1;sta

24. Swap Nodes in Pairs

Given a linked list, swap every two adjacent nodes and return its head.For example,Given 1->2->3->4, you should return the list as 2->1->4->3.Your algorithm should use only constant space. Y

141. Linked List Cycle

Given a linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?为了不另开内存,可以用快慢指针来判别,如果有环那么快指针肯定会追上慢指针;fast=fast->next->next;slow=slow->next;判
