is going to solve. The following example shows how to review the question:"Enter two numbers to obtain the maximum common number"Here, the question requires that it is unclear what the two numbers are. Is it an integer? Score? Real number? Plural? Such problems cannot be solved. Because the problem itself is not thorough and strict. When copying a question, you can also think about the specific requirements of the program and clarify the functions of the program. If necessary, you can further c
