题目描述:
自己的提交:
class Solution: def arraysIntersection(self, arr1: List[int], arr2: List[int], arr3: List[int]) -> List[int]: arr = arr1 + arr2 +arr3 res = [] for i in arr: if arr.count(i)==3 and i not in res: res.append(i) return res
另:
class Solution(object): def arraysIntersection(self, A, B, C): S = set(A) & set(B) & set(C) return sorted(S)
