/*
* ===敏感词匹配===
* 最大正向匹配，不符则回溯到上一个匹配的最长的子串。
* 分前中后缀，优先词根、然后前缀、然后后缀
* 优先搜索前后缀，其次归纳
*
* 匹配算法：
* 1. 循环搜索词根
* 1. 成功则将输入字符串的词根部分替换为结果中的替换字符串
* 2. 失败则将将起始位置后移一位重新开始搜索词根
* 2. 直到起始位置超出字符串，停止
*
* 词根搜索：
* 1. 循环匹配下一个字符
* 1. 如果该节点有result、prefix、suffix子节点，将该节点及该字符所对应的位置压入栈中
* 2. 直到匹配失败
* 1. 循环对栈中节点进行操作
* 1. 如果该节点有prefix子节点，则对其进行前缀搜索
* 1. 搜索成功，则返回搜索到的替换字符串以及该节点（词根栈中的节点）对应字符的位置
* 2. 如果该节点有suffix子节点，则对其进行后缀搜索
* 1. 搜索成功，则返回搜索到的替换字符串以及该节点（词根栈中的节点）对应字符的位置
* 3. 如果该节点有result子节点，则返回result节点中的内容作为替换字符串以及该节点（词根栈中的节点）对应字符的位置
* 4. 如果以上都没成功，则弹出下一个节点继续匹配
* 2. 直到栈为空，还没有搜索到替换字符串的话，返回匹配失败
*
* 前缀搜索：
* 1. 循环匹配下一个字符
* 1. 如果该节点有result、suffix子节点，将该节点及该字符所对应的位置压入栈中
* 2. 直到匹配失败
* 1. 循环对栈中节点进行操作
* 1. 如果该节点有suffix子节点，则对其进行后缀搜索
* 1. 搜索成功，则返回搜索到的替换字符串
* 2. 如果该节点有result子节点，则返回result节点中的内容作为替换字符串
* 3. 如果以上都没成功，则弹出下一个节点继续匹配
* 2. 直到栈为空，还没有搜索到替换字符串的话，返回匹配失败
*
* 后缀搜索：
* 1. 循环匹配下一个字符
* 1. 如果该节点有result子节点，将该节点及该字符所对应的位置压入栈中
