第一次参加这种比赛，虽然是c类赛事，但是是ccf主办的，难度还是有点的，主要是前面签到题主要是思想，后面的题目难度太高，身为力扣只刷了一百多道题目的我解决不了，这几道我只做了B,C题,E题超时了，这些题目的时间限制实在是太高了，这次只能是来学习学习了。顺便附上一下自己的代码，有点丑勿喷，希望有大神能出个题解，感谢

A题：

B题：

if __name__ in '__main__': Input = input() n,m = int(Input.split(' ')[0]),int(Input.split(' ')[1]) MIN = min(n,m) MAX = max(n,m) first_x = MIN first_y = MIN if n == m: k = 1 else: k = 2 if n<m else 3 for i in range(2): if k == 0: distance = min(n-first_x,m-first_y) first_x += distance first_y += distance elif k == 1: distance = min(first_x,first_y) first_x -= distance first_y -= distance elif k == 2: distance = min(first_x,m-first_y) first_x -= distance first_y += distance elif k == 3: distance = min(n-first_x,first_y) first_x += distance first_y -= distance flag = 0 if first_x == 0 and first_y == 0: k = 0 flag = 1 elif first_x == 0 and first_y == m: k = 3 flag = 1 elif first_x == n and first_y == 0: k = 2 flag = 1 elif first_x == n and first_y == m: k = 1 flag = 1 if flag == 0: if k == 0: if first_y == m: k = 3 elif first_x == n: k = 2 elif k == 1: if first_x == 0: k = 3 elif first_y == 0: k = 2 elif k == 2: if first_x == 0: k = 0 elif first_y == m: k = 1 elif k == 3: if first_y == 0: k = 0 elif first_x == n: k = 1 print(first_x,first_y)

C题：

if __name__ in '__main__': Input = input() n,m = int(Input.split(' ')[0]),int(Input.split(' ')[1]) n += 1 top = 1 while((n ** top) <= m): top += 1 top -= 1 temp = top nums = [] while(top > 0): num = m // (n**top) m -= num * (n**top) nums.append(num) top -= 1 if m > 0: nums.append(m) res = '' for i, snum in enumerate(nums): if snum == 0: temp -= 1 continue if temp > 1 and snum > 1: res += str(snum) + 'x^' + str(temp) + '+' elif temp > 1 and snum == 1: res += 'x^' + str(temp) + '+' elif temp == 1 and snum > 1: res += str(snum) + 'x+' elif temp == 1 and snum == 1: res += 'x+' else: res += str(snum) temp -= 1 print(res)
