glibc 2.9 之后的 strstr() 在一定情况下会用高效的 Two Way algorithm ,之前的版本是普通的二重循环查找,因此用不着自己写。 而且glibc 的作者一度也写错过,sourceware.org/bugzilla ps. strstr() 还不止一次出过 bug:sourceware.org/bugzillasourceware.org/bugzilla 等等。c - What is the fastest substring ...

我在试图对KMP算法进行编码。完成之后,我使用java string方法进行了尝试。pattern is at index 2Occurence of 3 pattern is at index 27 我知道java上述代码如何与KMP实现公平?另外,如果我在一个模式匹配案例的面试中给出了这个答案,而不是KMP,这是一种明智的做法还是我只是在浪费我的机会? 浏览0提问于2017-02-...
