HDU 6659 Acesrc and Good Numbers

Problem Description

Acesrc is a famous mathematician at Nanjing University second to none. Playing with interesting numbers is his favorite. Today, he finds a manuscript when cleaning his room, which reads

... Let f(d,n) denote the number of occurrences of digit d in decimal representations of integers 1,2,3,⋯,n. The function has some fantastic properties ...

... Obviously, there exist some nonnegative integers k, such that f(d,k)=k, and I decide to call them d-good numbers ...

... I have found all d-good numbers not exceeding 101000, but the paper is too small to write all these numbers ...

Acesrc quickly recollects all d-good numbers he found, and he tells Redsun a question about d-good numbers: what is the maximum d-good number no greater than x? However, Redsun is not good at mathematics, so he wants you to help him solve this problem.

 

 

Input

The first line of input consists of a single integer q (1≤q≤1500), denoting the number of test cases. Each test case is a single line of two integers d (1≤d≤9) and x (0≤x≤1018).

 

 

Output

For each test case, print the answer as a single integer in one line. Note that 0 is trivially a d-good number for arbitrary d.

 

 

Sample Input

3 1 1 1 199999 3 0

 

 

Sample Output

1 199990 0
