Use Java, Do not import any packages (only java.lang.*), write public static boolean func(int num)

It checks if all digits in num are in the same row or column of the numpad. If num only has 1 digit (0 - 9), it will count as in the same row or column. You can assume that num is not negative. The rows of the numpad are {0, 123, 456, 789}, and the columns are {0147, 0258, 0369}. Notice that 0 is a wildcard that counts for all three columns.

7	8	9
4	5	6
1	2	3
