Given two non-negative integers n1 and n2, where n1 < n2. The task is to find the total number of integers the range interval [n1, n2] ( e no repeated digits. 954210th inclusive) which 543 741 For example: Suppose n1 = 11 and n2 = 15. There is the number 11, which has repeated digits, but 12, 13, 14 and 15 have no repeated digits. So, the output is 4. Example 1: Input 954-Value of n1 - Value of n2 Output: 4 Example 2: Input: 101 95400Value of n1 Value of n2 Output: 72 95431016_113 95431016_113 954310 954310 954310 Constraints: . 1
