题目描述

Let's call a positive integer nn ordinary if in the decimal notation all its digits are the same. For example, 11 , 22 and 9999 are ordinary numbers, but 719719 and 20212021 are not ordinary numbers.

For a given number nn , find the number of ordinary numbers among the numbers from 11 to nn .

输入格式

The first line contains one integer tt ( 1t1041 \le t \le 10^4 ). Then tt test cases follow.

Each test case is characterized by one integer nn ( 1n1091 \le n \le 10^9 ).

输出格式

For each test case output the number of ordinary numbers among numbers from 11 to nn .
