First, the prefaceIt is well known that no matter which programming language is used, there is always a lot of dealings with strings. If the right programming language is used in string processing, the API is full, it can save a lot of trouble. As

Reprinted a paper on the string matching algorithm zzl. The picture is a bit problematic. Let's take a look. This algorithm is actually very simple! It is to first count the position of the first character of the feature string in the main string,

STD: String The reason why the char * string is discarded and the string class in the C ++ standard library is used is because it is compared with the former, and does not have to worry about whether the memory is sufficient, the string length, and

1. Stacks and heaps (heap) are places that Java uses to store data in RAM. Unlike C + +, Java automatically manages stacks and heaps, and programmers cannot directly set up stacks or heaps.2. The advantage of the stack is that the access speed is
