题目描述

An integer template is a string consisting of digits and/or question marks.

A positive (strictly greater than 00 ) 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:

  • 4242 matches 4?;
  • 13371337 matches ????;
  • 13371337 matches 1?3?;
  • 13371337 matches 1337;
  • 33 does not match ??;
  • 88 does not match ???8;
  • 13371337 does not match 1?7.

You are given an integer template consisting of at most 55 characters. Calculate the number of positive (strictly greater than 00 ) integers that match it.

输入格式

The first line contains one integer tt ( 1t21041 \le t \le 2 \cdot 10^4 ) — the number of test cases.

Each test case consists of one line containing the string ss ( 1s51 \le |s| \le 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 00 ) integers that match the template.
