Which statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function.   One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function.   Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.   One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function.
