题目:
Nezzar’s favorite digit among 1,…,9 is d. He calls a positive integer lucky if d occurs at least once in its decimal representation.
Given q integers a1,a2,…,aq, for each 1≤i≤q Nezzar would like to know if ai can be equal to a sum of several (one or more) lucky numbers.
Input
The first line contains a single integer t (1≤t≤9) — the number of test cases.
The first line of each test case contains two integers q and d (1≤q≤104, 1≤d≤9).
The second line of each test case contains q integers a1,a2,…,aq (1≤ai≤109).
Output
For each integer in each test case, print “YES” in a single line if ai can be equal to a sum of lucky numbers. Otherwise, print “NO”.
You can print letters in any case (upper or lower).
Example

2
3 7
24 25 27
10 7
51 52 53 54 55 56 57 58 59 60

YES
NO

Note
In the first test case, 24=17+7, 27 itself is a lucky number, 25 cannot be equal to a sum of lucky numbers.
