第一题，我是用python写的，感觉没啥问题，为什么AC只有55%.楼主能帮忙看一下吗 class Solution: def solve(self, a, b): tmp = [val for val in a if val in b] print(len(a) - len(tmp), len(b) - len(tmp), len(tmp)) N, a_num, b_num = map(int, input().split()) a = [int(i) for i in input().split()] b = [int(i) for i in input().split()] solution = Solution() solution.solve(a, b)
