standard output
Nezzar's favorite digit among 1,…,9">1,…,91,…,9 is d">dd. He calls a positive integer lucky if d">dd occurs at least once in its decimal representation.
Given q">qq integers a1,a2,…,aq">a1,a2,…,aqa1,a2,…,aq, for each 1≤i≤q">1≤i≤q1≤i≤q Nezzar would like to know if ai">aiai can be equal to a sum of several (one or more) lucky numbers.
Input
The first line contains a single integer t">tt (1≤t≤9">1≤t≤91≤t≤9) — the number of test cases.
The first line of each test case contains two integers q">qq and d">dd (1≤q≤104">1≤q≤1041≤q≤104, 1≤d≤9">1≤d≤91≤d≤9).
The second line of each test case contains q">qq integers a1,a2,…,aq">a1,a2,…,aqa1,a2,…,aq (1≤ai≤109">1≤ai≤1091≤ai≤109).
Output
For each integer in each test case, print "YES" in a single line if ai">aiai can be equal to a sum of lucky numbers. Otherwise, print "NO".
You can print letters in any case (upper or lower).

24=17+7">27">25">分析
24=17+7">27">25">题目需要判断一个数能否由几个幸运数组成,但a数组的范围是1e9
24=17+7">27">25">猜测大数据直接被屏蔽,可以得到d*10之后就都可以任意表示,因为10可以任意使用,个位也可以任意使用
24=17+7">27">25">小数据直接疯狂暴力即可
24=17+7">27">25">比赛的时候因为数组范围又疯狂wa了两次
