内容如标题，原题是小学四年级的一个动脑筋。

稍微改动一下，比如总数有N张牌，两人轮流抽'1－m'张，先抽几张，才能确保最后一张一定被自己或对手抽到。

python写的，代码如下：

def get_answer():    total = input('please input the number of total card:\n')    every_card = input('please input the number of everyone should take:\n')    last_status = input("please define take the last one win or lose:\n,win input '1', lose input '0'\n")    # last_status = True    loop_num = int(math.ceil(total / every_card))    for j in range(1, every_card + 1):        for i in range(loop_num):            if last_status:                if total == j + (i * (every_card + 1)):                    plan_dic = dict()                    plan_dic['first_take'] = j                    plan_dic['held_num'] = every_card + 1                    plan_dic['times'] = i                    print plan_dic            else:                if total == j + ((i - 1) * (every_card + 1)) + every_card:                    plan_dic = dict()                    plan_dic['first_take'] = j                    plan_dic['held_num'] = every_card + 1                    plan_dic['times'] = i                    print plan_dic

其实还可以再改动一下，比如N个人轮流抽，或许这样没有解的情况会比较多了。
