数据类型使用 long，int 类型只能过 2/3 的用例，排查了好久，怎么看都感觉代码没问题，就是过不了后面的用例，把 x,y,z 的数据类型全改成 long 就好了

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        while (in.hasNextLine()) {
            int n = in.nextInt();
            long h = in.nextLong();
            long[][] ints = new long[n][3];
            for (int i = 0; i < n; i++) {
                for (int j = 0; j < 3; j++) {
                    ints[i][j] = in.nextInt();
                }
            }
            in.nextLine();
            for (long[] i : ints) {
                long x = i[0];
                long y = i[1];
                long z = (h << 1) - i[2];
                long cd = gcd(gcd(x, y), z);
                System.out.println((x / cd) + " " + (y / cd) + " " + (z / cd));
            }
        }
    }

    private static long gcd(long a, long b) {
        a = Math.abs(a);
        b = Math.abs(b);
        while (b != 0) {
            long temp = b;
            b = a % b;
            a = temp;
        }
        return a;
    }
}
