题目描述
An integer template is a string consisting of digits and/or question marks.
A positive (strictly greater than 0 ) integer matches the integer template if it is possible to replace every question mark in the template with a digit in such a way that we get the decimal representation of that integer without any leading zeroes.
For example:
- 42 matches 4?;
- 1337 matches ????;
- 1337 matches 1?3?;
- 1337 matches 1337;
- 3 does not match ??;
- 8 does not match ???8;
- 1337 does not match 1?7.
You are given an integer template consisting of at most 5 characters. Calculate the number of positive (strictly greater than 0 ) integers that match it.
输入格式
The first line contains one integer t ( 1≤t≤2⋅104 ) — the number of test cases.
Each test case consists of one line containing the string s ( 1≤∣s∣≤5 ) consisting of digits and/or question marks — the integer template for the corresponding test case.
输出格式
For each test case, print one integer — the number of positive (strictly greater than 0 ) integers that match the template.
