限制循环范围
import java.util.Scanner;
// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
// 注意 hasNext 和 hasNextLine 的区别
while (in.hasNextInt()) { // 注意 while 处理多个 case
int t = in.nextInt();
int x = 0, y = 0, z = 0;
for (x = 0; x <= 100 / 5 ; x ++) {
for (y = 0 ; y <= (100 - 5 * x) / 3 ; y++) {
for (z = 0; z <= (100 - 5 * x - 3 * y) && z >= 0; z++) {
if ((x + y + 3 * z == 100) && (5 * x + 3 * y + z == 100)) {
System.out.println(x + " " + y + " " + 3 * z);
}
}
}
