LeetCode 349 Intersection of Two Arrays 解题报告
题目要求
Given two arrays, write a function to compute their intersection.
题目分析及思路
给定两个数组,要求得到它们之中共同拥有的元素列表(列表中元素是唯一的)。可以将所给数组转成集合,利用集合的交集的概念,最后将结果转成列表即可。
python代码
class Solution:
def intersection(self, nums1: List[int], nums2: List[int]) -> List[int]:
nums1, nums2 = set(nums1), set(nums2)
return list(nums1 & nums2)
