Language is an important symbol of human being different from other animals. Natural language is an oral language (voice) and written language (writing) that distinguishes interpersonal communication from formal or artificial languages such as logical and programming languag

Such schemes (or algorithms) are based on grammatical rules, are clear and easy to implement (in the case of a computer, several loops are judged). For programmers, such algorithms are also particularly cordial. Because the syntax rules of the Advanced programming languages (such as C + +) that programmers use are very similar to this scenario.
Because such algorithms are intuitive and easy to implement, it is believed that people can solve the problem of
