How learning algorithm

Method to read the program:

　　　　　　1. See the flow (i.e., step)

　　　　　　2. Look at the function

　　　　　　3. Test number

　　　　　　4. Knock, trial and error (if it does not understand the program and then knock)

algorithm:

　　Narrow algorithm is closely related to the storage of data

　　Independent of storage generalized algorithm and data

　　Generics: the use of technology to achieve some kind of effect is this: different storage methods, the same operation is performed
