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.

//B

#include<stdio.h>

int main (void){

    char s[102],c;
    int k,i,count=0;
    int check=0;

    scanf("%d",&k);

    for(i=0;i<=101;i++){
        scanf("%c",&s[i]);
        if(s[i]=='\n'){
            break;
        }
    }

    if(i<=k){
        printf("%s",s);

            printf("%c", s[i]);
        }
