凑数的，传说中的百钱百鸡，换汤不换药。

100匹马100袋粮食大马驮三袋小马驮两袋，两个小马崽驮一袋，问大马小马小马崽各多少匹？  java代码如何实现？

public class HowManyHorses {

    public static void main(String[] args) {

        final int HORSE_NUMBER = 100;

        final int FOODS_NUMBER = 100;

        for (int bigHorseNumber = 0; bigHorseNumber <= ( HORSE_NUMBER / 3 + 1 ); bigHorseNumber++) {

            for (int smallHorseNumber = 0; smallHorseNumber <= (HORSE_NUMBER / 2 + 1); smallHorseNumber++) {

                for (int ponyNumber = 0; ponyNumber <= HORSE_NUMBER; ponyNumber++) {

                    if (bigHorseNumber     + smallHorseNumber     + ponyNumber     == HORSE_NUMBER

                     && bigHorseNumber * 3 + smallHorseNumber * 2 + ponyNumber / 2 == FOODS_NUMBER

                     &&                                             ponyNumber % 2 == 0) {

                        System.out.println(bigHorseNumber + " " + smallHorseNumber + " " + ponyNumber);

                    }

                }

            }

        }

    }

}
