In the given range [L, R], print all numbers having unique digits. e.g. In range 10 to 20 should print all numbers except 11.

Example 1:

L = 10
R = 20

10 12 13 14 15 16 17 18 19 20

The number 11 has two 1 therefore
11 is not a unique number.

Example 2:

L = 1
R = 9

1 2 3 4 5 6 7 8 9

All the Numbers are unique.

Your Task:  
You don't need to read input or print anything. Your task is to complete the function uniqueNumbers() which takes two integers L and R as an input parameter and returns the list/vector of all the unique numbers present between L to R.

Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)

1 <= L <= R <= 104
