处理哈希冲突的几种方法：
开放定址法
开放定址法就是产生冲突之后去寻找下一个空闲的空间，其中又包括下面两种：
线性探测法：di= i ，或者其他线性函数。相当于逐个探测存放地址的表，直到查找到一个空单元，然后放置在该单元。
平方探测法：（https://python123.io/index/topics/data_structure/hash_table）
链表法
这是另外一种类型解决冲突的办法，散列到同一位置的元素，不是继续往下探测，而是在这个位置是一个链表，这些元素则都放到这一个链表上。
再散列
如果一次不够，就再来一次，直到冲突不再发生。

常见排序算法：归并 快排(面试题40) 拓扑(主要用来解决依赖问题，比如abcde五门课的学习之间有依赖关系，最后决定学习顺序以顺利完成学业等)
其他排序算法 桶排序、堆排序
