#include<stdio.h>
int main(void)
{
	char p[1001];
	int n,k,i,j,box,sum;
	scanf("%d %d",&n,&k);
	for(i=0;i<n;i++){
		scanf("%d",&p[i]);
	}
	for(i=0;i<n-1;i++){
		for(j=i+1;j<n;j++){
			if(p[i]>p[j]){
				box=p[i];
				p[i]=p[j];
				p[j]=box;
			}
		}
	}
	sum=0;
	for(i=0;i<k;i++){
		sum=sum+p[i];
	}
printf(	"%d\n",sum);
return 0;
