Nezzar's favorite digit among 1,…,91,…,9 is dd. He calls a positive integer lucky if dd occurs at least once in its decimal representation.

Given qq integers a1,a2,…,aqa1,a2,…,aq, for each 1≤i≤q1≤i≤q Nezzar would like to know if aiai can be equal to a sum of several (one or more) lucky numbers.

Input

The first line contains a single integer tt (1≤t≤91≤t≤9) — the number of test cases.

The first line of each test case contains two integers qq and dd (1≤q≤1041≤q≤104, 1≤d≤91≤d≤9).

The second line of each test case contains qq integers a1,a2,…,aqa1,a2,…,aq (1≤ai≤1091≤ai≤109).

Output

For each integer in each test case, print "YES" in a single line if aiai can be equal to a sum of lucky numbers. Otherwise, print "NO".

You can print letters in any case (upper or lower).

Example

input

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

output

YES
NO
YES
YES
YES
NO
YES
YES
YES
YES
YES
YES
NO

Note

In the first test case, 24=17+724=17+7, 2727 itself is a lucky number, 2525 cannot be equal to a sum of lucky numbers.

 

思路：對於任意的ai，如果ai大於等於10*d（這里有點不好判斷，賽中我判斷到大於100去了，就一直錯），一定能拆成n*10+m*d的形式（n和m是待定系數）或一個lucky數+m*d的情況，一定有解；對於小於10*d的數，如果能拆成n*10+m*d的形式（n和m是待定系數），則有解，否則無解。

const int maxn=1e4+7;
int t,n,d,y;
int main()

    cin>>t;
    while(t--)
    {
        cin>>n>>d;
        for(int i=1;i<=n;i++)
        {
            cin>>y;
            if(y>=10*d)
            {
                cout<<"YES"<<endl;
            }

                for(int j=1;j<=10;j++)
                {
                    int z=(j*d)%10;
                    if(z==y%10)
