Which algorithm is better? What if elements ofnums2are stored on disk, and the memory is limited such that you cannot load all elements into the memory at once? https://leetcode.com/problems/intersection-of-two-arrays-ii/ 把一个数组中的元素的元素对应到哈希表,key是值,value是出现的次数,然...
350. 两个数组的交集 II 题目来源:力扣(LeetCode)https://leetcode-cn.com/problems/intersection-of-two-arrays-ii 题目 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: [2,2] 1. 2. 示例2: 输入: nums1 = [4,9,5], nums2 = ...
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
349. Intersection of Two Arrays Intersection of Two Arrays 可以使用hash table保存下数组1的出现的元素,然后判断数组2中的各元素是否在数组1中出现过,但直接使用set更简单 class Solution(object): def intersection(self, nums1, nums2): """ :type nums1: List[int] ...
Write a Python program to find the intersection of two given arrays using Lambda. Original arrays: [1, 2, 3, 5, 7, 8, 9, 10] [1, 2, 4, 8, 9] Intersection of the said arrays: [1, 2, 8, 9] Click me to see the sample solution ...
Earlier in the chapter, we wrote a function that returned the intersection of two sequences (it picked out items that appeared in both). Here is a version that intersects an arbitrary number of sequences (1 or more), by using the varargs matching form *args to collect all arguments ...
