Given a range of elements, print the number of elements in the range without repeating digits. For example, the result for the range 10-13 is 3 (since 10, 12, and 13 are the valid numbers, but 11 is not because it has repeating digits).

Example 1: 

Input:  start = 10, end = 13
Output: 3 
Explanation:


The valid numbers in the range 10-13 are 10, 12, and 13. The number 11 is not valid because it has repeating digits. Therefore, the count of numbers without repeating digits is 3.
