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

The famous quote from Gaius Julius Caesar.

Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<string.h>

int main(int argc, char *argv[]){

  int k;
  scanf("%d", &k);

  char s[101];
  scanf("%s", s);

  int n;
  if(strlen(s)>k){
    n = k;
  }else{
    n = strlen(s);
  }
  for(int i=0; i<n; i++){
    printf("%c", s[i]);
  }
  if(strlen(s)>k){
    for(int i=n; i<strlen(s); i++){
      printf(".");
    }
  }
  printf("\n");

  return 0;
}
