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.

int main(){
    int k,p;
    char s[100],s1[100];
    
    scanf("%d",&k);
    scanf("%s",s);
    
    p=strlen(s);
    
    for(int i=0;i<k;i++)
    {
       s1[i]=s[i]; 
    }
    
    if(p>k)
    {
     printf("%s...",s1);   
    }
    else
    printf("%s",s1);
