standard output

You are given a multiset of n integers. You should select exactly k of them in a such way that the difference between any two of them is divisible by m, or tell that it is impossible.

Numbers can be repeated in the original multiset and in the multiset of selected numbers, but number of occurrences of any number in multiset of selected numbers should not exceed the number of its occurrences in the original multiset.

Input

First line contains three integers nk and m (2 ≤ k ≤ n ≤ 100 0001 ≤ m ≤ 100 000) — number of integers in the multiset, number of integers you should select and the required divisor of any pair of selected integers.

Second line contains n integers a1, a2, ..., an (0 ≤ ai ≤ 109) — the numbers in the multiset.

Output

If it is not possible to select k numbers in the desired way, output «No» (without the quotes).

Otherwise, in the first line of output print «Yes» (without the quotes). In the second line print k integers b1, b2, ..., bk — the selected numbers. If there are multiple possible solutions, print any of them.

又是道简单题啊qwq,就是菜鸟题目读的慢了点qwq。

题意:在n个数中取出k个数,使得这k个数两两之间的差都是m的倍数。

对每个数%m,余数相同那么它们的差就是m的倍数辣~~~

	scanf("%d%d%d",&n,&k,&m);
	for(int i=1;i<=n;i++){scanf("%d",&a[i]);q[i]=a[i]%m;}
	for(int i=1;i<=n;i++) sum[q[i]]++;
	bool flag=false;
