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).

K
S

Output

Print a string as stated in Problem Statement.

int main()
{
  int k;
  char s[101];
  
  if(strlen(s)>k)
  {
    for(int i = 1; i == k; i++)
    {  
    printf("%c", s[i]);
      if(i == k)
      {
        printf("...");
      }
