Given a range, print all numbers having unique digits.
Input : 10 20 Output : 10 12 13 14 15 16 17 18 19 20 (Except 11) Input : 1 10 Output : 1 2 3 4 5 6 7 8 9 10
As the problem is pretty simple, the only thing to be done is :- 1- Find the digits one by one and keep marking visited digits. 2- If all digits occurs one time only then print that number. 3- Else not.
1 2 3 4 5 6 7 8 9 10 12 13 14 15 16 17 18 19 20
