Populating Next Right Pointers in Each Node II

原题地址大意是，给定二叉树的每个节点都有一个next指针，希望能遍历一遍二叉树使每个节点的next指针指向其同一级的右侧节点（最右侧节点的next指针始终置为空）如：1 /\ 23 /\\ 457变换后：1->NULL /\ 2->3->NULL /\\ 4->5->7->NULL基本思路依然是按层序遍历(BFS)来设置指针。代码及解释如下：1usingnamespacestd;

3. Longest Substring Without Repeating Characters

Twopointers配合HashSet相当于控制一个小窗，如果下一个字母是新的字母，那小窗就往右移一格，同时检查一下是不是最大长度，如果下一个字母是有重复的，那么就让小窗的左侧往右移动到第一个不是该字母的地方
