无重复字符的最长子串（Longest Substring Without Repeating Characters）

LeetCode.jpg3.无重复字符的最长子串给定一个字符串，请你找出其中不含有重复字符的最长子串的长度。示例1:输入:"abcabcbb"输出:3解释:因为无重复字符的最长子串是"abc"，所以其长度为3。示例2:输入:"bbbbb"输出:1解释:因为无重复字符的最长子串是"b"，所以其长度为1。示例3:输入:"pwwkew"输出:3解释:因为无重复字符的最长子串是"wke"，所以其长度为3。

Longest Substring Without Repeating Characters 的 javascript 解法

分析本题最理想的状态是只遍历一遍字符串，为了在遍历的时候确定有无重复的字符，我们需要一个哈希表hash辅助查询，javascript中的对象可以充当哈希表的角色，键是某一个字符，值为该字符在字符串中的位置。在遍历的时候设置一个变量head指向子串的头，一个变量tail指向子串的尾，每次将tail的位置向后移一位，在哈希表中查询tail位置处的新字符，以hash中有无新字符来决定下一步的操作。想象一
