비교적 쉬운 문제인데 입력에 10^12 사이라고 되어있는데 처음에 Int로 받아 int범위를 초과한 값이 입력돼서... InputMismatchException이 계속 발생했다.... ㅎㄷㄷ... import java.util.Scanner; public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); long a = sc.nextLong(); long b = sc.nextLong(); long c = sc.nextLong(); System.out.println(a+b+c); } }
