* 返回true；string A：ABCD，string B：BCE，返回false；String A：ABCD，String B：AA，返回true。
*
* 思路：
* 思路一：遍历字符串B，判断每一个字符是否出现在字符串A中，时间复杂度O(n*m)，空间复杂度O(1);
* 思路二：先对两个字符串排序，然后同时遍历字符串A和B，判断B中的每一个字符是否都在字符串A中。时间复杂度O(nlogn)，空间复杂度O(1)；
* 思路三：将每一个字符映射到一个素数上，对字符串A中的每一个字符表示的素数，求累积；然后遍历字符串B，用每一个字符表示的素
* 数去除字符串A的累积，判断余数是否为0。时间复杂度：O(n)，空间复杂度O(1)。可能存在的问题：乘积时可能会溢出。
* 思路四：如果可以使用Java中的数据结构，HashMap和Set可以很方便地解决问题；如果不能，我们可以构造一个“签名”，将每一个字

z字形层次遍历是对层次遍历加上了一个限制条件（即相邻层，从左到右的遍历顺序相反），
我们取queue大小,就是上一层的结点数. for循环把这一层都加入进去,如果奇数层就第一个结点开始(因为上一层是偶数)先加右再加左.
如果偶数层就最后结点开始(因为上一层是奇数)先加左再加右.
一层结束深度增加,同时用一个栈,因为遍历下一层的数据 和输出这一层的数据 是刚好相反的..
data arraylist是因为他最后不要空格, 所以全部保存了再输出. 不然stack其实就有正确答案了,最后多一个空格.
