1416 - Restore The Array\. Hard 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. **Example 1:** **Input:** s = "1000", k = 10000 **Output:** 1 **Explanation:** The only possible array is [1000] **Example 2:** **Input:** s = "1000", k = 10 **Output:** 0 **Explanation:** There cannot be an array that was printed this way and has all integer >= 1 and <= 10. **Example 3:** **Input:** s = "1317", k = 2000 **Output:** 8 **Explanation:** Possible arrays are [1317],[131,7],[13,17],[1,317],[13,1,7],[1,31,7],[1,3,17],[1,3,1,7] **Constraints:** * 1 <= s.length <= 105 * `s` consists of only digits and does not contain leading zeros. * 1 <= k <= 109
