解三元一次方程组可以得出三种鸡的数量关系。。。

import java.util.*;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int count = sc.nextInt();

        int x;
        int y;
        int z;

        for (int i = 0; i <= 100; i += 4) {
            x = i;
            y = 25 - 7 * x / 4;
            z = 100 - x - y;
            if (x + y + z == 100 && z >= 0 && y >= 0) {
                System.out.println(x + " " + y + " " + z);
            }
        }
    }
