input

standard input

standard output

You're given an array a. You should repeat the following operation k times: find the minimum non-zero element in the array, print it, and then subtract it from all the non-zero elements of the array. If all the elements are 0s, just print 0.

Input

The first line contains integers n and k (1≤n,k≤105), the length of the array and the number of operations you should perform.

The second line contains n space-separated integers a1,a2,…,an (1≤ai≤109), the elements of the array.

Output

Print the minimum non-zero element before each operation in a new line.

Examples

Note

In the first sample:

In the first step: the array is [1,2,3], so the minimum non-zero element is 1.

In the second step: the array is [0,1,2], so the minimum non-zero element is 1.

In the third step: the array is [0,0,1], so the minimum non-zero element is 1.

In the fourth and fifth step: the array is [0,0,0], so we printed 0.

In the second sample:

In the first step: the array is [10,3,5,3], so the minimum non-zero element is 3.

In the second step: the array is [7,0,2,0], so the minimum non-zero element is 2.

#include<cstdio>
#include<algorithm>

using namespace std;
typedef long long LL;

const int maxn = 1e5+5;

int main() {
    LL a[maxn];
	int n, k;
	scanf("%d%d", &n, &k);
	for (int i = 0; i < n; i++) scanf("%lld", &a[i]);
	sort(a,a+n);
	LL temp = 0;
	int t = 0;
	while(k--) {
		if (t > n) {
			printf("0\n");
			continue;
		}
		temp += a[t];
		printf("%lld\n",a[t++]);
		while (a[t]-temp <= 0) {
			t++;
		}
		a[t] -= temp;
	}
	return 0;
}

刚开始这个代码一直过不了,问了大佬才知道,局部变量在栈内存分配空间,空间较小,会出现溢出,而全局变量存储在静态储存区分配内存,把LL a[maxn]放到主函数外边就可以了
