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.

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

#include <stdio.h>

int main()
{
	int a,K;
	char S[1000];

	scanf("%d",&K);

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

	if(a<=K)
	{
		for(int i=0;i<a;i++)
		{
			printf("%c",S[i]);
		}
	}
	else
	{
		for(int i=0;i<a;i++)
		{
			printf("%c",S[i]);
		}
		printf("...");
	}
	return 0;
