因为使用Arrays类的sort方法,所以时间复杂度是O(n log(n)),空间复杂度是O(n)。 publicint[]intersection3(int[] nums1,int[] nums2){ Set<Integer>set=newHashSet<>(); Arrays.sort(nums1); Arrays.sort(nums2);inti =0;intj =0;while(i < nums1.length && j < nums2.length) {if(nums1[i...
先将两数组排序,然后使用双指针,依次判断两数组中的元素是否相等,如果某个元素大于或小于另外一个元素,则将指针向后移动,如果相等,则将元素放入ArrayList中,然后将ArrayList中的元素迭代放入数组,最后返回。 因为使用Arrays类的sort方法,所以时间复杂度是O(n log(n)),空间复杂度是O(n)。 publicint[]intersect(int...
Given two arrays, write a function to compute their intersection. Example: Given nums1 = [1, 2, 2, 1], nums2 = [2, 2], return [2]. Note: 1、Each element in the result must be unique. 2、The result can be in any order. 要完成的函数: vector<int> intersection(vector<int>& ...
