问题：公鸡一仅仅5元，母鸡一仅仅3元，小鸡三仅仅1元。问100元能够买多少仅仅鸡？

using System;namespace ConsoleApplication1{    class Program    {        static void Main(string[] args)        {            int z, i=0;            for (int x = 0; x < 20; x++)                for (int y = 0; y < 33; y++)                {                    z = 100 - x - y;                    if (5 * x + 3 * y + z / 3 == 100 && z % 3 == 0)                        Console.WriteLine("{0}.公鸡：{1}"+'\t'+"母鸡：{2}"+'\t'+"小鸡:{3}",++i,x,y,z);                }            Console.ReadLine();        }    }}
