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....

The famous quote from Gaius Julius Caesar.

Solution in C (GCC 9.2.1) (judge verdict: Accepted)

#include<stdio.h>
int main()
{
    int K,i;
    scanf("%d",&K);
    char S[100000],l[10000];
    scanf("%s",&S);
    int length;
    length=strlen(S);

    if(length>K)
    {

        for(i=0; i<K; i++)
        {

            l[i]=S[i];
        }
          printf("%s...",l);


    }

    else
    {
         for(i=0; i<K; i++)
        {

            l[i]=S[i];

        }
        printf("%s",l);

    }


    return 0;
}
