Problem Statement

Snuke has N sticks.
The length of the i-th stick is l_i.

Snuke is making a snake toy by joining K of the sticks together.

The length of the toy is represented by the sum of the individual sticks that compose it.
Find the maximum possible length of the toy.

Constraints

1 \leq K \leq N \leq 50

1 \leq l_i \leq 50

l_i is an integer.

Input

Input is given from Standard Input in the following format:

N K
l_1 l_2 l_3 ... l_{N}

Output

Print the answer.

Sample Input 1

5 3
1 2 3 4 5

Sample Output 1

12

You can make a toy of length 12 by joining the sticks of lengths 3, 4 and 5, which is the maximum possible length.

Sample Input 2

15 14
50 26 27 21 41 7 42 35 7 5 5 36 39 1 45

Sample Output 2

386

#include <stdio.h>
int main(void){
int n,k,ans=0,count,count2,max=0,maxcount=0;
int suuretu[100];
scanf("%d",&n);
  scanf("%d",&k);
  for(count=0;count<=n-1;count++){
    scanf("%d",&suuretu[count]);
  }
  for(count2=0;count2<=k-1;count2++){
    for(count=0;count<=n-1;count++){
      if(suuretu[count]>max){
        max=suuretu[count];
        max=count;
      }
  }
  ans=ans+suuretu[count];
  suuretu[count]=0;
  }
  printf("%d",ans);
  return 0;
}
