( 13445 ) A Happy Birthday, Polycarp! PROGRAMMING implementation 1000

B'Hooray! Polycarp turned n years old! The Technocup Team sincerely congratulates Polycarp! Polycarp celebrated all of his n birthdays: from the 1 -th to the n -th. At the moment, he is wondering: how many times he turned beautiful number of years? According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: 1 , 77 , 777 , 44 and 999999 . The following numbers are not beautiful: 12 , 11110 , 6969 and 987654321 . Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10). Help Polycarpus to find the number of numbers from 1 to n (inclusive) that are beautiful. The first line contains an integer t ( 1 <= t <= 10^4 ) -- the number of test cases in the input. Then t test cases follow. Each test case consists of one line, which contains a positive integer n ( 1 <= n <= 10^9 ) -- how many years Polycarp has turned. Print t integers -- the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between 1 and n , inclusive. In the first test case of the example beautiful years are 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 and 11 . '...
