[ICPC 2024 NAC] Champernowne Substring
题目描述
The Champernowne string is an infinite string formed by concatenating the base-10 representations of the positive integers in order.
It begins
It can be proven that any finite string of digits will appear as a substring in the Champernowne string at least once.
Given a string of digits and question marks, compute the smallest possible index that this string could appear as a substring in the Champernowne string by replacing each question mark with a single digit from to . Each question mark can map to a different digit. Since this index can be large, print it modulo .
输入格式
The first line of input contains a single integer (), which is the number of test cases.
Each of the next lines contains a string () consisting of digits to or question marks.
输出格式
Output lines. For each test case in order, output a single line with a single integer, which is the smallest possible index where the string could appear as a substring in the Champernowne string, modulo .
