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:**

Input:L = 10 R = 20Output:10 12 13 14 15 16 17 18 19 20Explanation:The number 11 has two 1 therefore 11 is not a unique number.

**Example 2:**

Input:L = 1 R = 9Output:1 2 3 4 5 6 7 8 9Explanation: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)

**Constraints:**

1 <= L <= R <= 10^{4}
