To give the particular number the largest possible value, arrange the digits in the order of their individual value, beginning with the largest one on the left and smallest on the right. To give the particular number its smallest possible value, arrange the digits in the order of their individual value, beginning with the smallest one on the left and largest on the right.
The largest ten digit number with no repeated digits is '9876543210'.
On a calculator screen it is eight(8) digits.
The largest 4-digit number with two different digits is 9998. Its successor is the next number, which is 9999. However, 9999 has only one digit (9), so we need to find the next valid 4-digit number with two different digits. This number is 10000, which is technically a 5-digit number, so the largest valid number with two different digits before 9999 is 9998, and its successor cannot be a 4-digit number with two different digits. Thus, there is no valid successor that meets the criteria.
