There was a bored person in the group who talked about a math problem. So I also tried programming. The Code is as follows: Int A = 0, B = 0, c = 0, D = 0, x = 0, F, G, H, I, ABCD, fghi; The clever use of C # Is that the result is converted to a string. then, the contains (string a) method is applied to check whether the query result contains the four digits in the previous section and the value is 0. The value is determined by the lenght attribut
