然后又看到了350. Intersection of Two Arrays II,这次的结果是两个数组的交集,但是可以有重复元素了,要运行O(n)的话,这次直接想到了用空间换时间,无非是使用hash了,Python的字典就是hash实现的,于是写了: 1classSolution(object):2defintersect(self, nums1, nums2):3"""4:type nums1: List[int]5:type ...

python 两个数组的交集 intersection of two arrays,给定两个数组,写一个函数来计算它们的交集。例子:给定num1=[1,2,2,1],nums2=[2,2],返回 [2].提示:每个在结果中的元素必定是唯一的。我们可以不考虑输出结果的顺序。classSolution(object):defintersection(self,nums1,n
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] Note:

每天一算:Intersection of Two Arrays leetcode上第349号问题:Intersection of Two Arrays 给定两个数组,编写一个函数来计算它们的交集。 示例 1: 输入: nums1 = [1,2,2,1], nums2 = [2,2] 输出: [2] 示例 2: 输入: nums1 = [4,9,5], nums2 = [9,4,9,8,4] 输出: [9,4] 说明:...
If you want to get the intersection of arrays, use the intersect1d() method. Intersection means finding common elements between two arrays.
