this is essentially different from a function or method in the traditional sense: the function and the way have the execution process, have the input and the output, the functor and the predicate are only the information in the Knowledge base storage way, through the query function.Exercise 1.5 assumes that we have the following Knowledge Base:Wizard (Ron).Haswand (Harry).Quidditchplayer (Harry).Wizard (x):-Hasbroom (x), Haswand (x).Hasbroom (x):-Quidditchplayer (x).How will prolog respond to t

The answer in this blog is not from official resources, but from my own exercises. If you have any questions or errors, please discuss them. 11-12.Transfer functions. Write a sister function for the testit () function described in this chapter. Timeit () carries a function object (with parameters) and calculates the amount of time it takes to execute the function, rather than the error during testing. Return the following status: function return value
