C ++ learning note 36: the explicit and explicit instantiation of the template, and the learning note 36 C ++ templates may not be able to process certain types. For example: #include Compilation result: You can see many errors. (Although this is not the focus .) Suppose I want mSwap to only exchange the data of two man, and the name remains the same as the original one. What should we do? At this time,

Note 1: recursion; Note: Recursion At the beginning, I talked about the analysis of the space complexity and time complexity of the algorithm. How did the algorithm come from and how it evolved step by step? I have read the path of the algorithm before. This is a bit familiar with it, is the specific example of the time complexity analysis is not very good Yes, you should exercise more. After all This is a
