Given a string s[0…len−1], please calculate the length of the longest common prefix of s[i…len−1] and s[0…len−1] for each i>0. I believe everyone can do it by brute force. The pseudo code of the brute force approach is as the following: We are wondering, for any ...

Pattern First Exact String Matching The Java language lacks fastStringsearching algorithms.String“indexOf(…)” and “lastIndexOf(…)” operations perform a naive search for the provided pattern against a source text. The naive search is based on the “brute force” pattern first exact string ...
The basic idea of the algorithm can be relaxed to improve the brute force algorithm (and we'll see just how good a relaxed algorithm is at the end in the performance shootout): instead of calculating a long hash, why not use a "micro-hash" of comparing equality for the single first ...

Using matching variables other than the minimum set we defined would dramatically improve the efficiency of the records matching. For example, parents name or the city of birth is a very discriminatory matching variable. Furthermore, the first name seems to be less reliable than the birth name ...

First, we passed the user-agent string to the parser, requesting it to determine the browser. The parser brute-force iterated up to a few hundred regexes one by one, seeing if any of them had a match on the user-agent string. The first regex that produced a match would have its resul...
