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: Each element in the result must be unique. The…

设计的很烂的一道题 List<Integer> res = new ArrayList<>(); // int l1 = nums1.length; // int l2 = nums2.length; // int l = 0; // while (l<l1&&l<l2) // { // if (nums1[l]==nums2[l]) // res.add(nums1[l]); // l++; // } // int[] nums = new int[r…
