Right ouput but showing wrong answer.

Add Natural Numbers Problem Code: ADDNATRL

Output is correct but after submission its showing wrong answer
My Code
/* package codechef; // don’t place package name! */

import java.util.;
import java.lang.
import java.io.*;

/* Name of the class has to be “Main” only if the class is public. /
class Codechef
public static void main (String[] args) throws java.lang.Exception
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int sum=0;
sum = (n

n*(n+1) might become long number, declare n and sum as long in place of int.
