A program was supposed to print an array of integers. The program forgot to print whitespaces and the array is printed as a string of digits s and all we know is that all integers in the array were in the range [1, k] and there are no leading zeros in the array.
Given the string s and the integer k, return the number of the possible arrays that can be printed as s using the mentioned program. Since the answer may be very large, return it modulo 109 + 7.
\n
Example 1:
\n\n\nInput: s = "1000", k = 10000\nOutput: 1\nExplanation: The only possible array is [1000]\n\n\n
Example 2:
\n\n\nInput: s = "1000", k = 10\nOutput: 0\nExplanation: There cannot be an array that was printed this way and has all integer >= 1 and <= 10.\n\n\n
Example 3:
\n\n\nInput: s = "1317", k = 2000\nOutput: 8\nExplanation: Possible arrays are [1317],[131,7],[13,17],[1,317],[13,1,7],[1,31,7],[1,3,17],[1,3,1,7]\n\n\n

Constraints:
\n\n1 <= s.length <= 105s consists of only digits and does not contain leading zeros.1 <= k <= 109Compiled with clang 11 using the latest C++ 17 standard.
