有没有人能够确定哪些算法用于包括哪些内容？方法在Ruby中？例如

 HelloWorld的.INCLUDE？（你好）
 

解决方案

作为的压花的在他的回答状态，字符串＃包括电话 rb_str_index 。反过来这个函数调用 rb_memsearch ，它实现了拉宾-Karp字符串搜索算法，根据这个帖子对红宝石论坛.COM 。

Is anyone able to pinpoint which algorithm is used for the include? method in Ruby? For example

"helloworld".include?("hello")

As emboss states in his answer, String#include calls rb_str_index. This function in turn calls rb_memsearch, which implements the Rabin-Karp string search algorithm, according to this post on ruby-forum.com.
