https://leetcode-cn.com/problems/intersection-of-two-arrays-ii/ 描述 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 = [9,4,9,8,4] 输出: [4,9] 1 2 说明: ...
https://leetcode-cn.com/problems/intersection-of-two-arrays-ii/ 描述 给定两个数组,编写一个函数来计算它们的交集。 示例 1: 示例 2: 说明: 输出结果中每个元素出现的次数,应与元素在两个数组中出现的次数一致。 我们可以不考虑输出结果的顺序。 进阶: 如果给定的数组已经排好序呢?你将如何优化你的算法?
