题目描述

Let's call a positive integer $n$ ordinary if in the decimal notation all its digits are the same. For example, $1$ , $2$ and $99$ are ordinary numbers, but $719$ and $2021$ are not ordinary numbers. For a given number $n$ , find the number of ordinary numbers among the numbers from $1$ to $n$ .

The first line contains one integer $t$ ( $1 \le t \le 10^4$ ). Then $t$ test cases follow. Each test case is characterized by one integer $n$ ( $1 \le n \le 10^9$ ).

For each test case output the number of ordinary numbers among numbers from $1$ to $n$ .
