| * 检测字符串编码（注意：存在误判的可能性，降低误判的几率的唯一方式是给出尽可能多的样本$line） | |
| * 检测原理：对给定的字符串的每一个字节进行判断，如果误差与gb18030在指定误差内，则判定为gb18030；与utf-8在指定误差范围内，则判定为utf-8；否则判定为utf-16 | |
| * @param string $line | |
| * @return string 中文字符集，返回gb18030（兼容gbk,gb2312,ascii）；西文字符集，返回utf-8（兼容ascii）；其他，返回utf-16（双字节unicode） | |

Simply put, a keyspace "MISS" means some piece of data you tried to retrieve from Redis was not there. This usually means that one of the following things happened:

##08722 – Data Structurefor application programmers 这门课主要是开给EBIZ和MISM的，在MISM那边的课号是95772. 但是很多ECE, INI的同学，以及咱ME转CS帮都在上这门课。这门课只有半学期，一共6个credits，相当于1.5学分。内容非常基础，但是我觉得帮助挺大的，对于非CS科班出身想转CS的同学非常建议上一下， 基础越弱收获越大，要是基础比较硬的话就不用上了。LZ上的其它CS的课几乎都是各种牛校的PHD出身，这门课的老师好像都没有PHD学位，肯定没法去上15的课，但是讲课挺用心，讲的也很清楚。讲课这东西真的不是老师自己越牛就讲的越好。尤其数据结构这种比较基础的内容。这门课从最简单的内容讲起，包括array, arraylist, linked list, stack, queue,sorting(bubble, selection, insertion, merge, quick, heap), hashTable, hashMap,hashSet, BST, TreeMap, TreeSet, Huffman coding, Heap. 每周一次quiz, lab, homework。讲的时候内容都围绕Java Collection 来讲，还涉及与collection有关的comparator, iterator 等内容。这门课完全就是针对面试的，作业要求先手写代码（虽然大部分时候都是先ECLIPSE敲好再抄到纸上的）。
6次homework，前面的非常简单，后面稍微麻烦一点，难度都不大，就是让你去熟悉这些数据结构能自己implement，也能用JAVA COLLECTION。
