Problem Statement

We have a string S consisting of lowercase English letters.

If the length of S is at most K, print S without change.

If the length of S exceeds K, extract the first K characters in S, append ... to the end of them, and print the result.

Constraints

K is an integer between 1 and 100 (inclusive).

S is a string consisting of lowercase English letters.

The length of S is between 1 and 100 (inclusive).

Input

Input is given from Standard Input in the following format:

K
S

Output

Print a string as stated in Problem Statement.

Sample Input 1

7
nikoandsolstice

Sample Output 1

nikoand...

nikoandsolstice has a length of 15, which exceeds K=7.

We should extract the first 7 characters in this string, append ... to the end of them, and print the result nikoand....

Sample Input 2

40
ferelibenterhominesidquodvoluntcredunt

Sample Output 2

ferelibenterhominesidquodvoluntcredunt

int main()
{
  int K; char S[256]={0};
  scanf("%d\n",&K);
  for(int i=0;i<256;i++){
    scanf("%c",&S[i]);
  }
  if(strlen(S)<=K){
    printf("%s",S);
  }else{
    for(int i=0;i<K;i++){
      printf("%c",S[i]);
    }
    printf("...");
  }
  return 0;
