今日头条的模拟题一直显示运行失败！！但是电脑上运行的好好的

import java.math.BigInteger;
import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		int n = scan.nextInt();
		int num = 1;
		BigInteger a1, b1, c1;
		while (n > 0) {
			a1 = new BigInteger(scan.nextInt() + "");
			b1 = new BigInteger(scan.nextInt() + "");
			c1 = new BigInteger(scan.nextInt() + "");
			if ((a1.add(b1)).compareTo(c1) == 1) {
				System.out.println("Case #" + num + ": true");
			} else {
				System.out.println("Case #" + num + ": false");
			}
			n--;
			num++;
		}
		scan.close();
	}
}
