5x+3y+z/3=100
设公鸡为x-enumeration method (exhaustive) "Benren Regulation" : all possible test of January 1, and selected eligible for the results output. Cases -- 100 yuan to buy a 100 chicken : 100 yuan to buy 100 chickens. Known rooster 5 yuan / only, the hen 3 yuan / only and chicken one yuan / 3.
