Given two arrays, write a function to compute their intersection. Example 1: Input: nums1 = [1,2,2,1], nums2 = [2,2] Output: [2] Example 2: Input: nums1 = [4,9,5], nums2 = [9,4,9,8,4] Output: [9,4] 思路 代码 class Solution { public int[] intersection(int…

问题描述: Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: Each element in the result must be unique. The result can be in any order. my answer: 思路: 遍历nums1里的元素,看nums2…

Given two arrays, write a function to compute their intersection. Example:Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: Each element in the result must be unique. The result can be in any order. 这道题让我们找两个数组相同的部分,难度不算大,我们可以用个set把nums1都…

最近,在用解决LeetCode问题的时候,做了349: Intersection of Two Arrays这个问题,就是求两个列表的交集.我这种弱鸡,第一种想法是把问题解决,而不是分析复杂度,于是写出了如下代码: class Solution(object): def intersection(self, nums1, nums2): """ :type nums1: List[int] :type nums2: List[int] :rtype: List[int] &q…
